I discovered a Fossil on the Seashore and Puzzled
Updated on March 22, 2017 Kathi moreContact Author Discovering Frequent Fossils on Nice Lakes Beaches
A favourite past time for many is combing the beaches for interesting gadgets the surf washes in. Whether or not you’re strolling alongside the shoreline of the ocean or the great Lakes in the USA, your imagination is on high alert to select one thing up you simply cannot cross by! Out of the blue, something catches your eye! However, it’s not driftwood or seaside glass and even a fairly rock. You might not know exactly why, but you suspect you found one thing that was as soon as a residing creature.
Has this ever occurred to you A deep sense of curiosity and childlike imagination drives us to seek out out what we may have picked up alongside our saltwater or freshwater shorelines. Having collected fairly a couple of samples from Lake Michigan’s shoreline, myself, I lastly decided one day to meet my nagging curiosity and followed via with a rewarding investigation. The more I discovered about my stony sand-smoothed findings, the extra I needed to know. I puzzled what the creatures might have seemed like when alive and the way they survived. I additionally wished to understand how they showed up so prevalent alongside the fresh water beaches. Some time later, after many answered questions, I can actually say I enjoy a cool pastime. Taking things a step further, I’ve drawn illustrations of their dwelling beings and started a fossil site. You could find the hyperlink at the top.
A few of essentially the most prevalent fossils found alongside the nice Lake’s beaches are crinoids (shown in the images to the proper). They have been coined with a a number of names as a result of animal’s options and by the character of their fossils found throughout historical past. One widespread identify for them is “Indian Beads”. Native People have been recognized to make necklaces with their broken up pieces which resemble the form of beads excellent for stringing. They’ve also been known as “Lucky Stones”! Spotting one takes a eager eye as a lot of the items are fairly small.
As dwelling creatures, every circular part was stacked one over the other constructing the animal’s complete framework. They possessed branching arms that sat atop lengthy single stems. They have been sessile creatures, in different words, they remained attached to the sea floor. Some varieties are identified to have towered several meters in length. Their unfastened construction resulted in the residing organism’s beautifully colored and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny food particles passing by on ocean currents with their feathery community of arms that functioned like traps. Crinoids fit into the phylum of Echinoderm, which means spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s prolonged history began through the Ordovician Period around 500 million years in the past, though most fossils are from the Mississipian Period around 345 mya and are preserved in limestone. Right this moment there are far fewer species and most lack the long meandering stem common in Paleozoic varieties.
Within the course my investigation, I had typically questioned why so many crinoid fossils ended up along the nice Lakes; significantly by the truth that they had thrived in saltwater environments. I’ve since realized they can be discovered widespread in North America. Part of the answer to my inquiry is simple enough to explain. Throughout their lifetime, much of the world’s continents had been lined under heat shallow oceans, including elements of North America. So how is it their fossils are so frequent near the big lakes The reply is because ten thousand years in the past when the giant glaciers sculpted the deep basins forming the good Lakes, they also dug into the deep layers the place their remains rested. In the method, they had been deposited the place we now can uncover them and revel of their secrets and techniques, in addition to that of different species from the identical period.
Another widespread seashore find, bryozoans are sometimes known as lace corals because of their delicately threaded appearance, but they don’t seem to be true corals. Instead, they are moss-like animals belonging to the household of Fenestellida for their fan-shaped, mesh appearance. They reside in tight colonies sculpted by exhausting, limy, branching structures. The colony consists of thousands of individual animals called “zooids”. Each individual zooid lives inside its personal limy tube known as a zooecium. The zooecium are the size of sewing needles. A single zooid begins the colony. A bryozoan colony has been noticed rising from a single zooid to 38,000 in simply 5 months. Every extra zooid is a clone of the very first one.
Fascinating how they feed, Every zooid has an opening by means of which the animal can prolong its ring of tentacles called lophophores. Their lophophores seize microscopic plankton from the water passing by. If one zooid receives meals, it nourishes the neighboring zooids as a result of they’re joined by strands of protoplasm. If solely we people could possibly be extra like them ensuring everybody on the planet is fed!
Their fossil record dates back 500 mya with 15,000 known species. Immediately there are about 3,500 dwelling species.
I found these clam fossils on the shore of Oval Beach in Southwestern Michigan. The shell of the darker sample has been completely replaced by minerals and is petrified to stone. Its easy surface is a telltale demonstration of the lake’s sand and water motion. The lighter coloured sample clearly reveals the hardened muddy sediment that has completely encrusted its shell.
“Clam” generally is a time period that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s surface. Bivalve oysters and mussels attach themselves to laborious objects and scallops can free swim by flapping their valves together. All types lack a head and often have no eyes, though scallops are a notable exception. With the use of two adductor muscles they can open and close their shells tightly. Very fittingly, the phrase “clam” gives rise to the metaphor “to clam up”, which means to cease speaking or listening.
Bivalves have occupied Earth as early as the Cambrian Interval 510 million years in the past, however they were particularly abundant through the Devonian Interval around 400 million years in the past. Their fossils are discovered in all marine ecosystems and most commonly in close to shore environments. In 2007, off the coast of Iceland, a clam was discovered to be at the very least 405 years old. It was declared the world’s oldest dwelling creature by North Wales, Bangor University researchers.
No different organisms typify the Age of Invertebrates more than brachiopods. They’re essentially the most plentiful Paleozic stone island sconti fossils, except for possibly trilobites. Paleontologists use them so far rocks and different fossils. Numerous billions accumulated on the ocean flooring with over 30,000 kinds. At present there are far fewer species, only about 300 which dwell mostly in cold water, deep ocean environments.
Brachiopods appear like clams however are very different inside. To inform them apart, clams have uneven shaped shells, however each top and bottom halves are identical. Brachiopods are symmetrical at a look, but the bottom shell is smaller. Brachiopods are commonly called “lampshells” because of their similarity in shape to a Roman oil lamp.
They live in communities attached to objects by a muscular foot called a pedicle. They pressure water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
During the Devonian time slot, over 350 million years in the past, Michigan was covered by a shallow saltwater sea. That is the place mass colonies of corals called Hexagonaria, percarinata, commonly often known as Petoskey Stones, thrived and flourished. The saltwater seascape should have been lit up with a quilt-work of colours by the mass colonies. Unfortunately, they turned extinct at the top of the Permian Period’s mass extinction.
The identify “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan city was named after him, only the identify was modified to Petoskey. Due to their abundance along Michigan shorelines, especially in the northern areas close to Petoskey, Governor George Romney signed a bill in 1965 that made the Petoskey Stone the official state stone.
When observing one of the fossils, every coral hexagon structure, visible to the eye, held a single animal which opened a mouth to expose tentacles. The tentacles took in food and were also used to sting any organism or different corallite that came too close. Calcite, silica and other minerals replaced the original corallite exoskeleton.
An extinct order of coral called tabulate corals additionally formed reefs and lived in heat shallow waters throughout the same period because the Petoskey Stone corals. They had been the favosite corals. The tabulae (horizontal inside layers) had been constructed outward as the organism grew. These layers can clearly be seen within the photograph to the right. The favosites will also be identified by the honeycomb pattern on the exterior of their fossilized stays.
Hope you’ve got enjoyed my fossil discoveries. Next time you go to the seaside, keep your eyes open for a fossil discovery of your individual. You are welcome to make use of my hub or go to my fossil weblog to help make an identification!

Nice introduction to fossils and fossil trying to find learners Kathi.
I like the road:
‘A deep sense of curiosity and childlike imagination drives a few of us to search out out what we picked up alongside the freshwater shoreline.’
That is the unlucky point I feel. For some purpose, as individuals develop out of childhood too many lose their childhood fascination for such things as fossils, as well as other wonders like the creatures which stay in a pond, or the stars to be seen within the night time sky. That’s sad – if only everybody could keep that sense of curiosity and imagination as they grow up – the world can be a much more wondrous place for all – adults, in addition to children.
I hope some no less than really feel impressed as they stroll along a shoreline or beside a cliff face, to turn over just a few stones and see what they’ll discover. Alun

Yes, Fossillady, I did enjoy this. This has been an afternoon of learning. I have learn so many fascinating articles this afternoon and this one is definitely one I will remember. I had no thought. It is wonderful how much there is to learn about fossils.
Sending many Angels your means this afternoon. 🙂 ps

Hey this is so cool i simply bought my first fossil and wana speak with individuals abot this stuff . someone text me haha
Hey Micky, good to see you, sorry so late as I have been so busy these days with new jobs and all! I miss the common contact with all my hubber pals! Thanks for the great remark, you’re very variety to say so! Hope every thing is great with you! Hugs my friend

Your hubs are so pretty! Thank you expensive Fossillady!
Ha, What do you know, I am a geo-jokster and do not even realize it…hee
Ha fossillady something new…LOL and were speaking about fossil Ha that’s an incredible geo-joke…
Extraordinarily happy with this dialogue Tom and Birdy, discovered one thing new!!!!!
I assume it is sort of a tree with the circles. Attention-grabbing.
I am pretty certain the accretion strains on the highest of a clam will reveal its age-like the rings on a tree the clam will get bigger and another ring is added-

I’ll speak fossils with you any day. I’m in touch with each sides of my brain! Sometimes I surprise myself, lol.
“In 2007, off the coast of Iceland, a clam was found to be at least 405 years outdated. It was declared the world’s oldest dwelling creature by North Wales, Bangor College researchers.” How do they know this and the place is the clam at now How does one determine the age of a clam that has seen centuries move Oh, I believe a poem just came to thoughts. Each sides of that brain are reacting at the identical time.
Thanks for a fantastic and effectively researched Hub.
Very kind of you Janet! I had by no means worked with pastels before so there’s plenty of room for enchancment, they are mostly focused for kids! Next time you’re at the beach or in nature I hope you’ll be able to acknowledge some of these fossils!

Very interesting hub,Fossillady !Very informative and I really like the artwork! It is awesome.I never knew a few of these have been fossils! Well,I sure learned Stone Island Jackets something tonight!
Thanks for sharing each info and art…nice combo!
i know its kinda funny I at all times appreciated Ross too and my spouse would always take a look at me when he would say one thing geological…
don’t be concerned- publish a fossily hub i’ll learn it…
ya got one fan…its a begin
I do know what you mean, nobody wants to talk about fossils with me either. Jogs my memory of Ross on Friends. He at all times desires to share his information about fossils and the others will not have anything to do with it!lol
I’m just glad to talk fossils ith somebody- my children likem but.. even they tire of trying fast
Great advice Tom, Very a lot appreciated!
When cleaning crinoids- ya gotta know what kinda rock stone island sconti is clinging to them- will depend on the rock type you findem in around here it iseasily present in shale i normally rtry to clip off- the most effective i can with toe nail clippers – be careful- then i will use a reasonably dilute HCL solution between .1 and .25 dilute-use a “mushy wire brush” maybe nylon brush-ajust hcl to rockhardness- all the time use acid in wellventilated space use security glasses and neoprene or nitrile gloves- sandstone embeds- may be picked off the crinoids and a remaining acid wash
Hi Workingmom, Good to see you right here! I want I had advise for cleaning fossils, I would suppose so long as you do not use anything too harsh,it will likely be okay!
It feels like it’s not all that onerous for you to seek out the crinoids the place you might be! I get so excited every time I can spot one! lol…take care!

Love this hub! I was actually fascinated about writing a hub about crinoid beads (really about utilizing them to create jewellery, since I try this). My husband is an amateur archaeologist (aka rock hound), and he started taking me with him when we first began courting. I did not care a lot about discovering the arrowheads that he was searching, however I fell in love with the beads! We have been simply down in Monroe Co.KY, and found quite just a few inside a couple of minutes by some of the many creeks. By the best way, do you know a good method for cleaning fossils I need to clean these beads if I’m going to make jewellery out of them!
Hello Tom,Oh it feels like a rick fossil find space. I have by no means found a trilobite, my husband did as soon as while working on the railroad. I like to seek out crinoids which can be still attach, but it would be even higher to seek out one totally intact! Thanks for stopping by!

We have now the sme devonian aged fossils close to Lake Erie- that shallow sea was actually huge when my son went looking with me he stated what are all these nuts and washers doing here-on the ground in fact we have been in a crinoid wealthy area. There have been a ton of Brac’s s effectively-then we discovered some smaller trilobite halves and a had an important time diggin the dirt and shale shards He stored pulling up shale and asking what it was then he gave me one with a Trilobite trace fossil (imprint) it was actually a good one
Hi WillStarr, You made your kids feel very special that day! A wonderful fatherly factor to say. I would like to go to Kentucky and check out the shale financial institution. Kentucky has several fossil websites I’ve examine! I acknowledge you from different hubs and that i see you’re now following me, right back at ya!
WillStarr 6 years ago from Phoenix, Arizona
The Kentucky farm the place we lived for a couple of years had a shale bank on one facet of a stream that was loaded with fossils. My children had been fascinated once i advised them they had been looking at the beginnings of life on Earth, and that their eyes had been the first human eyes to ever see what they had found.
Nice, I’m glad you made a brand new discovery, I hope you find a lot of fossils! It actually is fun when you find one! It is gratifying later when you possibly can establish it!

Wowwee! Great hub. I stay in Long Island New York, where there are miles and miles of beaches. I by no means knew among the things I used to be taking a look at could possibly be fossils. When the weather is warmer I’ll revisit your hub to look and be taught extra. Thanks for educating me. Rated up and awesome.
My jaw dropped while you mentioned coelacanth fish that was found! I’ve read that too! I might love to return there and fossil hunt. I’ve by no means been across the ocean. Hope to try this before my day comes round!
Nell Rose 6 years ago from England
Hi, you must come over to England, you would have an ideal time! lol the final time I went to Lyme Regis, Jurassic coast, they have been filming for Tv, and they’d a fossil programme crammed with all that they had found, I might imagine that there are still a great deal of what we believe to be extinct animals still out there residing in the deep ocean, I remember studying that fishermen found a coelacanth fish nonetheless living back in 1933, and i imagine they’ve caught a couple of extra since then, so that you by no means know! cheers nell
Well, you have got made my day and that i hope yours is stuffed with love and joy! Hugs

Love this article very a lot…so informative..so fascinating…and I like your little drawings in addition to these superior photographs. I will probably be again for increasingly more!!
As a matter of fact I’m engaged on one partly thanks to your encouragement! It is way appreciated!
..Howdy Kathi – sure I like to walk alongside my beach within the spring, summer season and fall and decide up ‘found objects’ and flotsam and jetsam washed in from the tide particularly after a storm or high winds but as I speak there may be so much snow and ice down there right now you can’t see anything except a big blanket of white – in all places you look – I imagine I may have to wait till the spring now to discover something new and get again to my days of ‘beachcombing’ …….when you have any extra images about your days at the seaside or simply around where you reside it could be good to see you make another photographic hub on that subject ……

I can’t assist however feel sorry for poor deaf kitty, but I am positive he/she’s in good palms. We’ve got the same lake impact on the west coast of Michigan brought on by the westerly winds. In actual fact we’re in a snow belt area. Final couple of years we’ve had document snowfall over one hundred twenty inches. Do you choose up fossils while you stroll the seaside Thanks again on your assist!

…completely fascinating hub topic you have got written about here …. I stay on the northern shores of Lake Erie in Ontario, Canada and i walk on a regular basis along my seaside with my deaf cat (on a leash). I stay a hundred ft away from the lake ……and that i all the time see flotsam and jetsam and located objects that are washed up on a daily basis whether it be man made or miracles of natures.
By the best way how is the weather where you reside
We often get what is called lake impact situations due to the winds off the lake.
Again you’ve got really carried out some fantastic analysis here in your hub and can be a worthy addition in any classroom!
