Sir_Andrius Posted February 24, 2017 Share Posted February 24, 2017 (edited) Hello, my name is Andres. I found this in "La Pedrera beach" in Uruguay. At first I had no clue of what it was. I'm prone to think it is a sponge fossil, but would want help in this matter. I found it vaguely buried in the sand close to the shore. The sand of that beach is grainy and loaded with lots of shells of many mollusc species. If it is indeed a sponge fossil, what species it would be? Thanks in advance!

ynot Posted February 24, 2017 Share Posted February 24, 2017 Welcome to TFF! It could be a sponge (not My field of interest), but it looks like a burrow cast to Me. Wait for the sponge people to reply. Tony 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Guguita2104 Posted February 24, 2017 Share Posted February 24, 2017 It looks like a burrow,indeed! I've already found some poriferans and this doesn't look like one. Regards, Link to comment Share on other sites More sharing options...

doushantuo Posted February 25, 2017 Share Posted February 25, 2017 It COULD be a sponge,but a microscopical view would tell infinitely more.If diagenesis hasn't obliterated the microstructure,you might see spicules/desmas/scleres(=sponge needles). Sponges have pores as well. 1 Link to comment Share on other sites More sharing options...

This was probably made by some sort of decapod (perhaps a mud shrimp). Regards, Link to comment Share on other sites More sharing options...

fifbrindacier Posted March 1, 2017 Share Posted March 1, 2017 I agree with a burrow cast, i have some similar to yours. Regards.
