Lyn Posted March 5, 2015 Share Posted March 5, 2015 I thought his was just a blob of old concrete, but upon closer inspection that doesn't appear to be the case. Link to comment Share on other sites More sharing options...

luluboo1 Posted March 5, 2015 Share Posted March 5, 2015 Agreed. A cluster of horn corals. Very nice. Link to comment Share on other sites More sharing options...
piranha Posted March 5, 2015 Share Posted March 5, 2015 Acrocyathus (= Lithostrotion) proliferus is a common rugose coral from the Mississippian of Alabama and a good possible match for this specimen. Here is an excellent recent paper on this subject: Rodríguez, S., & Kopaska-Merkel, D.C. (2014) Mississippian rugose corals from Alabama: a review. Journal of Paleontology, 88(5):829-850 figure from: Sando, W.J. (1983) Revision of Lithostrotionella (Coelenterata, Rugosa) from the Carboniferous and Permian.

Herb Posted March 6, 2015 Share Posted March 6, 2015 Lithostrotion looks like a good id to me also "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.

minnbuckeye Posted March 6, 2015 Share Posted March 6, 2015 Just a question about rugasa corals. I always envisioned them growing individually on the sea floor. By the looks of these two pictures,they appear to definitely be clustered. The reason I ask is I create scenes for local teaching institutions with my fossils. I have always placed the horned corals as an individual scattered on the bottom. Should I cluster groups of them together? Link to comment Share on other sites More sharing options...
Auspex Posted March 6, 2015 Share Posted March 6, 2015 They were solitary organisms, but some could be reef-builders in the right environment.

piranha Posted March 6, 2015 Share Posted March 6, 2015 They were solitary organisms, but some could be reef-builders in the right environment. The posted specimen (Acrocyathus) is a colonial rugose coral. Link to comment Share on other sites More sharing options...
