Fossils from Michigan's Tropical Seas 

You helped me identify one of my fossils tonight! Thanks! Rock-ing video!

The highlight of my collection is an articulated clam shell with hounds tooth calcite inside. I found it at a rock quary in Northern Michigan.

Very informative video however the camera wobbles made me dizzy!

Thank you, John, for this entertaining and very educational synopsis in describing the marine life that thrived in the ancient tropical oceans during the Devonian Period, The Age of Fishes. Several RU-vid participants that i follow present vlogs on collecting cobbles and pebbles, many of which are host to fossils that you describe. Your excellent lecture is essential for anyone wishing to prospect in the rocks along the shores of Lakes Michigan and Superior.

So very, very interesting !!!

OOOOMG!!!! I FINALLY KNOW WHAT IT IS THAT I'VE FOUND. I have a chain link fossil l I found while Petoskey stone hunting on the Rifle River in Sterling Michigan

Petoskey stones can be found anywhere in Michigan

Omg and that trident thing...I thought it was a ancient birds foot print. Mine is quite large and I found it in Rockwood Michigan.

I found a fossil bigger than my hand it is awesome

Hi I'm from Philippines..I found in the mountains a crystalized honeycomb coral fossil...it is valuable for now?

So the days were shorter?

Highly informative. I am a Creationist so we differ on time :) However, the fossils are amazing.

This is really good, but the Moroccan stuff is a bit jarring.
