Some Marine Fossils!

old digger · Jul 17, 2013

Here are some marine fossils that were found above 6000 feet in elevation. If anyone wishes to help in their indentity please do so. I found the first one, and a friend of mine found the other three.

This last one is a much larger version of the one that I found, (Top).

Those are really neat looking! How do you know they're marine fossils though? I'm not saying they aren't, but I'd like to know for my own curiosity. Thank you!

The first and last fossils are good examples of Stromatolites, the second one is probably a form of sponge or bryozoan and the last one is coral, maybe favosite?

Nice. Weathering has really brought the specimens out of the matrix. I used to use HCL acid... what a nightmare. Look at some geology or paleontology maps of the fossiliferous zone to get more info on the formations.

Mostly from experience and collaboration with my friend.

Thanks for your input! Am I correct that the first and last one are similar to a type of Sea Anemone?

I will check this out. I do understand that the mountain range that these specimens were found is much older than the other mountain ranges in the area. Thanks for your input!
