nemocoral Posted May 11, 2017 Share Posted May 11, 2017 This is another picture with a ruler so you can tell the size of the sponge that I posted the other day. Perhaps it will help in identifying it.. Thank you. Link to comment Share on other sites More sharing options...
Micah Posted May 12, 2017 Share Posted May 12, 2017 Can you post a closeup of the surface that makes you think sponge? Link to comment Share on other sites More sharing options...
TqB Posted May 12, 2017 Share Posted May 12, 2017 Still saying Chaetetes. It forms massive sheets in some places, also domes and sub-spherical forms. Tarquin Link to comment Share on other sites More sharing options...

Micah Posted May 12, 2017 Share Posted May 12, 2017 Couldn't it just as easily be Syringopora? I'm not confident enough to make a call without seeing the the surface better. Link to comment Share on other sites More sharing options...
Micah Posted May 12, 2017 Share Posted May 12, 2017 This is from Kansas, so similar geology. I've found it to be helpful in the past. http://www.kgs.ku.edu/Publications/Bulletins/76_3/ Link to comment Share on other sites More sharing options...

It's not like Syringopora at all which is a mass of separate tubes with tubular cross connections. The closeups on the other post are spot on for Chaetetes. http://www.thefossilforum.com/index.php?/topic/74194-fossil-identification/#comment-781395 Tarquin Link to comment Share on other sites More sharing options...
