ID tail bones (I think) + misc bones

Recommended Posts

Mamasaurus

My family stumbled across quite a few pieces of fossilized bone over the weekend in Southeast Wyoming. We counted 40+ pieces that are between 2-6” in height and oval in shape. They were spread out over an area approx 40’ wide. We also found what might be a tooth along with sereral other unidentifiable pieces. This was a very exciting find for us and I would love to learn more about what (or who) we found! Please let me know if you need additional photographs or any other info.

Welcome to TFF!

Sorry, but those are not bone.

They are  (most of them) baculite shell pieces.

Thanks for the info and for your quickly replies! I obviously have a lot to learn! Any idea what the roundish one is?

if you touch the white part of this one to the tip of your tongue, does it stick?

Inoceramids "bivalves" or clams if you wish.

In the Dallas Tex area these sometimes produce pearls.

Yes, if I touch the white part it does stick to my tongue.

Unless there is visible bone structure (which I don't see in the photo), my guess is that this one is coprolite! :yay-smiley-1:

My husband (and daughter) would be SO excited if they are coprolite. Lol

Was there shell material on the outside?

Part of the surrounding rock chipped off and revealed the Shell material today when I went to take the new pics - sorry for not posting a better pic initially!

No problem - I study coprolites, so I get excited whenever I see potential :D

The fractal patterns on baculites never ceases to amaze me. It’s awesome how fundamental mathematical formulas manage to work their way into nature.

 

that was a pretty nerdy comment...

The roundish ones are indeed Inoceramid clams.  Both are common in certain late Cretaceous marine deposits around here (by which I mean all of Wyoming).  I don't see any teeth in your pix.  Just clams and baculites.

The baculite is beautiful. I love baculites, but they are hard to find here in Texas. 

The beautiful pattern you see are called suture lines. The little teeth like projections on the end of the baculite pieces are called septa.
