Tabulate (Simuliar)

Species: Un-known Coral
Formation: Eagleford (Arcadia Park member)
Upper Cretaceous
Location: Dallas Co. (Loop 12 corridor) West side

I have not been able to find any satisfactory information on this species.
When found it was as a collective colony of thousands, some in clusters of 3-100 having side by side growth connection to the one next to it.
I have not found them in any other local Arcadia Park member or otherwise.
If you have any information or you would need additional photos do not hesitate to post or ask.
I have a thousand+ of these some in multiple clusters of two three or more, most in small clusters of three or four.
All collected within an area ~10 Ft by 10 Ft.
I am open to information as to grouping or identification.
