Benjaminpb Posted August 14, 2017 Share Posted August 14, 2017 I found this in a local creek here in central Texas and I think it's part of a sand dollar encased in limestone. I'm probably wrong though. Any ideas? Thank's! Link to comment Share on other sites More sharing options...
Macrophyseter Posted August 14, 2017 Share Posted August 14, 2017 Hmm.. I've never heard of a sand dollar pattern as seen near the rim. Can you tell us where exactly you found it (like name of creek, nearest settlement, area name, etc), it actually helps us alot. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...

caldigger Posted August 14, 2017 Share Posted August 14, 2017 Here are a couple of pictures off Google for some Texas echinoids, compare to what you have. 2 Link to comment Share on other sites More sharing options...
Benjaminpb Posted August 14, 2017 Author Share Posted August 14, 2017 Thanks for the pictures. However, I have a few of those. From what I understand, those are sea urchins. This appears to be more flat than an urchin. I'm thinking that maybe it's a broken sand dollar. I'm actually hoping I'm wrong because being wrong is more interesting.

ynot Posted August 14, 2017 Share Posted August 14, 2017 It does look like a sand dollar, but it is to worn to say much more. Darwin said: " Man sprang from monkeys."

Max-fossils Posted August 14, 2017 Share Posted August 14, 2017 I'm pretty sure that it's from some kind of (very worn) sea urchin. Here are pieces of worn sea urchins in my collection. They come from a beach near Sevilla, Spain; so not at all from the same location. But the pattern is very similar.

fifbrindacier Posted August 15, 2017 Share Posted August 15, 2017 I agree it looks like a worn urchin. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

abyssunder Posted August 15, 2017 Share Posted August 15, 2017 It is a partial worn fossil echinoid. The ambulacral double-rows of pores (the petal region) are still visible. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

The first sand dollars appeared in the Eocene. 1 Link to comment Share on other sites More sharing options...
Benjaminpb Posted August 17, 2017 Author Share Posted August 17, 2017 I did not know that. That's what I love about the fossil forum. I learn something new every day! 1 Link to comment Share on other sites More sharing options...
