Paleozoic rugose coral? Devonian microcyclus? Please ID

[Nuna]

This came from San Saba County, Texas; found in fluviatile terrace deposits (Qt).  I would love to know more about this fossil.  Thank you for your input.

I don't think there's much more to say! Microcyclus looks spot on and I can't find any genera that look closer (though I don't have any recent literature on this sort). Lovely find.

Microcyclus seems accurate to me.  I don't know about reported Texas occurances, but the genus has been reported from New Mexico so Texas seems likely.

Thank you! I'll take any literature on them if you have recommendations or suggested links.  Did these become extinct before the end of Paleozoic Era?

Thank you for your help!  I read in a blog that these are common in Eastern Canada down to NY, and the ones down here were glacially distributed.  If you could point me towards more resources about this coral that would be fantastic.  Do you know when these became extinct?  Thanks again, appreciate the assistance.

This genus is just Devonian - Middle Devonian, according to the Treatise on Invertebrate Paleontology (part F, supplement 1) which is the only reference I have that names it. 

 

The last rugose corals became extinct by the end of the Permian.

Wow, how interesting.  My thanks and appreciation to you!

I found a very close match in U of Texas publication 4401 to a Pennsylvanian coral from San Saba County in Texas: Cumminsia aplata.

That's convincing, good job!

Cumminsia is a much better match in my opinion. Especially since most of the rock in your area is Pennsylvanian in age. Still a very nice find no matter the era it is from.

You are my HERO! Thank you so much, I got goosebumps when I saw this post.  I am so thrilled to have this identified.   Thanks again

I've learned something new, as I had not heard of this genus before.  Thanks!

Excellent, I appreciate the literature suggestions indeed. Thanks!
