I found a Fossil on the Beach and Questioned
Up to date on March 22, 2017 Kathi moreContact Creator Discovering Frequent Fossils on Great Lakes Beaches
A favorite past time for many is combing the beaches for attention-grabbing items the surf washes in. Whether or not you’re walking along the shoreline of the ocean or the good Lakes within the USA, your imagination is on high alert to select one thing up you simply can’t pass by! Suddenly, one thing catches your eye! However, it is not driftwood or beach glass or even a pretty rock. You could not know exactly why, but you suspect you discovered one thing that was as soon as a dwelling creature.
Has this ever happened to you A deep sense of curiosity and childlike imagination drives us to seek out out what we might have picked up along our saltwater or freshwater shorelines. Having collected fairly just a few samples from Lake Michigan’s shoreline, myself, I lastly decided sooner or later to satisfy my nagging curiosity and adopted via with a rewarding investigation. The more I realized about my stony sand-smoothed findings, the more I wished to know. I questioned what the creatures could have appeared like when alive and the way they survived. I additionally wished to know how they showed up so prevalent along the fresh water beaches. Some time later, after many answered questions, I can truthfully say I get pleasure from a cool pastime. Taking issues a step further, I have drawn illustrations of their living beings and began a fossil site. You can find the hyperlink at the top.
Some of essentially the most prevalent fossils discovered alongside the great Lake’s beaches are crinoids (proven within the images to the best). They have been coined with a several names as a result of animal’s features and by the character of their fossils discovered throughout history. One widespread identify for them is “Indian Beads”. Native Individuals have been identified to make necklaces with their broken up pieces which resemble the form of beads perfect for stringing. They’ve also been referred to as “Lucky Stones”! Spotting one takes a keen eye as many of the pieces are quite small.
As living creatures, each circular section was stacked one over the other constructing the animal’s whole framework. They possessed branching arms that sat atop long single stems. They were sessile creatures, in other phrases, they remained attached to the sea ground. Some varieties are recognized to have towered several meters in size. Their loose structure resulted in the residing organism’s beautifully coloured and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny meals particles passing by on ocean currents with their feathery community of arms that functioned like traps. Crinoids match into the phylum of Echinoderm, meaning spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s prolonged history started in the course of the Ordovician Interval around 500 million years ago, though most fossils are from the Mississipian Period round 345 mya and are preserved in limestone. In the present day there are far fewer species and most lack the lengthy meandering stem common in Paleozoic varieties.
In the course my investigation, I had typically questioned why so many crinoid fossils ended up along the good Lakes; particularly by the truth that they had thrived in saltwater environments. I’ve since realized they are often discovered widespread in North America. Part of the answer to my inquiry is straightforward enough to clarify. During their lifetime, a lot of the world’s continents had been coated under heat shallow oceans, including parts of North America. So how is it their fossils are so common close to the big lakes The reply is as a result of ten thousand years ago when the enormous glaciers sculpted the deep basins forming the great Lakes, they also dug into the deep layers the place their stays rested. In the process, they had been deposited the place we now can discover them and revel of their secrets, in addition to that of different species from the identical era.
Another widespread beach find, bryozoans are often referred to as lace corals due to their delicately threaded look, but they don’t seem to be true corals. Instead, they’re moss-like animals belonging to the family of Fenestellida for their fan-formed, mesh appearance. They reside in tight colonies sculpted by arduous, limy, branching structures. The colony consists of thousands of particular person animals referred to as “zooids”. Every 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 five months. Each additional zooid is a clone of the very first one.
Attention-grabbing how they feed, Each zooid has an opening by way of which the animal can extend 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 are joined by strands of protoplasm. If only we people could be more like them making certain everybody on the planet is fed!
Their fossil record dates back 500 mya with 15,000 identified species. In the present day there are about three,500 residing species.
I discovered these clam fossils on the shore of Oval Seaside in Southwestern Michigan. The shell of the darker pattern has been completely changed by minerals and is petrified to stone. Its smooth surface is a telltale demonstration of the lake’s sand and water motion. The lighter coloured pattern clearly reveals the hardened muddy sediment that has fully encrusted its shell.
“Clam” generally is a term that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s floor. Bivalve oysters and mussels attach themselves to hard objects and scallops can free swim by flapping their valves together. Every kind lack a head and usually have no eyes, though scallops are a notable exception. With using two adductor muscles they can open and close their shells tightly. Very fittingly, the word “clam” offers rise to the metaphor “to clam up”, which means to cease talking or listening.
Bivalves have occupied Earth as early as the Cambrian Period 510 million years in the stone island heat reactive jacket for sale past, but they had been notably plentiful through the Devonian Period round four hundred million years ago. 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 found to be at least 405 years old. It was declared the world’s oldest living creature by North Wales, Bangor University researchers.
No different organisms typify the Age of Invertebrates more than brachiopods. They are the most ample Paleozic fossils, aside from perhaps trilobites. Paleontologists use them so far rocks and different fossils. Numerous billions accumulated on the ocean flooring with over 30,000 forms. Today there are far fewer species, solely about 300 which live principally in cold water, deep ocean environments.
Brachiopods appear like clams but are very totally different inside. To inform them apart, clams have uneven shaped shells, but both top and bottom halves are similar. Brachiopods are symmetrical at a glance, but the bottom shell is smaller. Brachiopods are commonly called “lampshells” as a result 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 lined by a shallow saltwater sea. That’s where mass colonies of corals called Hexagonaria, percarinata, generally 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. Sadly, they turned extinct at the top of the Permian Interval’s mass extinction.
The name “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan metropolis was named after him, only the identify was modified to Petoskey. Because of their abundance along Michigan shorelines, especially in the northern regions near Petoskey, Governor George Romney signed a invoice in 1965 that made the Petoskey Stone the official state stone.
When observing one of the fossils, every coral hexagon structure, seen to the attention, held a single animal which opened a mouth to expose tentacles. The tentacles took in meals and had been also used to sting any organism or other corallite that got here too shut. Calcite, silica and other minerals replaced the unique corallite exoskeleton.
An extinct order of coral referred to as tabulate corals also formed reefs and lived in heat shallow waters during the same interval as the Petoskey Stone corals. They have been the favosite corals. The tabulae (horizontal internal layers) were constructed outward because the organism grew. These layers can clearly be seen within the picture to the suitable. The favosites can be identified by the honeycomb sample on the exterior of their fossilized remains.
Hope you’ve got loved my fossil discoveries. Next time you visit the beach, keep your eyes open for a fossil discovery of your personal. You’re welcome to make use of my hub or visit my fossil weblog to help make an identification!

Good introduction to fossils and fossil looking for rookies Kathi.
I like the line:
‘A deep sense of curiosity and childlike imagination drives a few of us to seek out out what we picked up along the freshwater shoreline.’
That’s the unfortunate level I believe. For some cause, as people grow out of childhood too many lose their childhood fascination for such issues as fossils, in addition to different wonders just like the creatures which live in a pond, or the stars to be seen in the night sky. That is unhappy – if solely everyone may keep that sense of curiosity and imagination as they grow up – the world could be a way more wondrous place for all – adults, as well as children.
I hope some at least feel impressed as they walk stone island heat reactive jacket for sale alongside a shoreline or beside a cliff face, to turn over a few stones and see what they can find. Alun

Sure, Fossillady, I did get pleasure from this. This has been an afternoon of studying. I’ve read so many interesting articles this afternoon and this one is unquestionably one I’ll remember. I had no idea. It’s amazing how a lot there may be to find out about fossils.
Sending many Angels your method this afternoon. 🙂 ps

Your hubs are so fairly! Thanks pricey Fossillady!
Ha, What are you aware, I’m a geo-jokster and do not even understand it…hee
Ha fossillady something new…LOL and were speaking about fossil Ha that’s a great geo-joke…
Extraordinarily pleased with this dialogue Tom and Birdy, realized one thing new!!!!!
I suppose it is sort of a tree with the circles. Interesting.
I’m pretty certain the accretion traces on the top of a clam will reveal its age-just like the rings on a tree the clam will get bigger and another ring is added-

I’ll talk 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 a minimum of 405 years outdated. It was declared the world’s oldest residing 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 pass Oh, I think a poem simply came to thoughts. Each sides of that brain are reacting at the identical time.
Thanks for a terrific and nicely researched Hub.
Very kind of you Janet! I had by no means worked with pastels before so there’s lots of room for enchancment, they’re mostly focused for youngsters! Next time you’re at the beach or in nature I hope you can acknowledge some of these fossils!

Very interesting hub,Fossillady !Very informative and I love the artwork! It is superior.I never knew a few of these have been fossils! Effectively,I sure learned one thing tonight!
Thanks for sharing each information and artwork…nice combo!
i do know its kinda funny I at all times liked Ross too and my spouse would at all times look at me when he would say something geological…
don’t be concerned- post a fossily hub i am going to read it…
ya received one fan…its a start
I know what you mean, nobody desires to talk about fossils with me both. Jogs my memory of Ross on Mates. He at all times wants to share his information about fossils and the others won’t have something to do with it!lol
I am simply glad to speak fossils ith somebody- my kids likem but.. even they tire of looking quick
Nice recommendation Tom, Very much appreciated!
When cleaning crinoids- ya gotta know what kinda rock is clinging to them- relies on the rock kind you findem in round here it iseasily found in shale i often rtry to clip off- one of the best i can with toe nail clippers – be careful- then i’ll use a reasonably dilute HCL resolution between .1 and .25 dilute-use a “delicate wire brush” maybe nylon brush-ajust hcl to rockhardness- always use acid in wellventilated area use security glasses and neoprene or nitrile gloves- sandstone embeds- might be picked off the crinoids and a ultimate acid wash
Hi Workingmom, Good to see you right here! I want I had advise for cleaning fossils, I might assume as long as you do not use something too harsh,it will be okay!
It seems like it is not all that arduous for you to find the crinoids the place you might be! I get so excited at any time when I can spot Island one! lol…take care!

Love this hub! I was truly eager about writing a hub about crinoid beads (truly about using them to create jewellery, since I try this). My husband is an amateur archaeologist (aka rock hound), and he began taking me with him once we first started courting. I didn’t care a lot about discovering the arrowheads that he was looking, but I fell in love with the beads! We have been simply down in Monroe Co.KY, and found fairly just a few within a couple of minutes by a few of the numerous creeks. By the way in which, have you learnt a great technique for cleaning fossils I need to scrub these beads if I’ll make jewelry out of them!
Hi Tom,Oh it appears like a rick fossil discover space. I’ve by no means discovered a trilobite, my husband did as soon as whereas working on the railroad. I like to seek out crinoids which are nonetheless attach, nevertheless it could be even better to seek out one totally intact! Thanks for stopping by!
We now have the sme devonian aged fossils near Lake Erie- that shallow sea was really huge when my son went searching with me he stated what are all these nuts and washers doing here-on the bottom in fact we have been in a crinoid rich area. There were a ton of Brac’s s well-then we found some smaller trilobite halves and a had an amazing time diggin the dirt and shale shards He kept pulling up shale and asking what it was then he gave me one with a Trilobite hint fossil (imprint) it was actually an excellent one
Hi WillStarr, You made your children feel very particular that day! A beautiful fatherly thing to say. I might like to go to Kentucky and check out the shale bank. Kentucky has several fossil websites I’ve examine! I recognize you from different hubs and i see you are now following me, proper again at ya!

The Kentucky farm the place we lived for a couple of years had a shale financial institution on one facet of a stream that was loaded with fossils. My children have been fascinated after i instructed them they had been trying at the beginnings of life on Earth, and that their eyes were the primary human eyes to ever see what they’d discovered.
Nice, I’m glad you made a new discovery, I hope you discover plenty of fossils! It actually is fun when you discover one! It’s gratifying later when you may identify it!

Wowwee! Nice hub. I stay in Long Island New York, where there are miles and miles of beaches. I never knew a few of the things I used to be looking at could possibly be fossils. When the weather is warmer I’ll revisit your hub to look and study extra. Thanks for educating me. Rated up and superior.
My jaw dropped while you talked about coelacanth fish that was found! I’ve read that too! I would love to come there and fossil hunt. I’ve by no means been across the ocean. Hope to do this earlier than my day comes around!
Nell Rose 6 years in the past from England
Hi, it’s best to come over to England, you’ll have an important time! lol the last time I went to Lyme Regis, Jurassic coast, they had been filming for Tv, and that they had a fossil programme stuffed with all they’d discovered, I might think about that there are still a great deal of what we consider to be extinct animals nonetheless out there residing within the deep ocean, I remember reading that fishermen found a coelacanth fish still dwelling again in 1933, and that i imagine they’ve caught just a few extra since then, so you by no means know! cheers nell
Nicely, you have made my day and that i hope yours is filled with love and joy! Hugs

As a matter of fact I am engaged on one partly thanks to your encouragement! It is far appreciated!
..Howdy Kathi – yes I like to stroll alongside my seaside within the spring, summer season and fall and choose up ‘discovered objects’ and flotsam and jetsam washed in from the tide particularly after a storm or excessive winds but as I converse there may be a lot snow and ice down there right now you can’t see something except a big blanket of white – in all places you look – I think about I could have to wait till the spring now to discover something new and get back to my days of ‘beachcombing’ …….when you’ve got any extra pictures about your days on the beach or just around where you reside it can be nice to see you make one other photographic hub on that subject ……

I can’t help but feel sorry for poor deaf kitty, however I am positive he/she’s in good hands. We now have the same lake effect on the west coast of Michigan caused by the westerly winds. The truth is we’re in a snow belt space. Final couple of years we’ve had file snowfall over a hundred and twenty inches. Do you decide up fossils if you stroll the beach Thanks again for your help!

…absolutely fascinating hub topic you have written about right here …. I stay on the northern shores of Lake Erie in Ontario, Canada and that i stroll everyday alongside my seashore with my deaf cat (on a leash). I reside 100 toes away from the lake ……and that i at all times see flotsam and jetsam and found objects that are washed up on a daily basis whether or not or not it’s man made or miracles of natures.
By the way in which how is the weather the place you reside
We often get what is called lake impact situations due to the winds off the lake.
Again you have really completed some wonderful research right here in your hub and could be a worthy addition in any classroom!
