I_gotta_rock Posted August 13, 2019 Share Posted August 13, 2019 I'll be darned if I can figure out what type of life form this is. At first I thought brachiopod, but no. Middle Devonian, Hamilton Group, New York. I refuse to give up my childish wonder at the world. Link to comment Share on other sites More sharing options...

Auspex Posted August 13, 2019 Share Posted August 13, 2019 Is the orientation presented 'top-side-up', as far as the sediments show? Were these sediments disturbed pre-lithification?

Fossildude19 Posted August 13, 2019 Share Posted August 13, 2019 Looks like a squish-out, ... possible a gastropod, or pelecypod. I find many like this from Deep Springs Road. The shell filled with mud, then successive layers of mud/sediment buried the item quickly, and weight was so much as to fracture the shell, and cause the mud inside to "squish-out". 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

I haven't ruled it out, but wouldn't that structure on the underside then be distorted and flattened? I refuse to give up my childish wonder at the world.

I_gotta_rock Posted August 14, 2019 Author Share Posted August 14, 2019 @marguy, It DOES look like a button coral of some sort, except that there is no evidence of coat structure. No pores of any shape or description. It's smooth, with faint signs of lines radiating from the center, mostly visible at the edges. I refuse to give up my childish wonder at the world.

Not necessarily. While many of the ones I find have the fossil as a part of the loose piece, I can see where the loose piece might have broken in such a way as to leave some of the fossil in the host rock. They are, after all, crushed/broken "shells". 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
