Heteromorph posted a topic in Fossil IDOn November 27 of this year my mother and I went hunting in a new housing development exposing the Austin Chalk in North Texas. The first and only site that we got to was covered in this rock that has been brought in from somewhere else. It was odd in that it looked like someone had just poured a bunch of it in an empty lot in no particular pattern. It was all next to a man made hole in the ground in the middle of the lot, but I don't see how that could be related. We have seen bags of this matrix in drainage ditches before and had also seen it variously thrown about at different Austin Chalk
DPS Ammonite posted a topic in Fossil IDI found these coral fossils in the Lower Cretaceous Weno Formation (or possible Paw Paw Fm), in northern Grayson County in northern Texas. The rock is a silty ironstone with lots of marine shells. The corals are about 5mm across and about 1-1.5mm thick. I think that they might be Microbacia sp. Has anyone found similar corals in the Weno Fm or other areas of similar age? Any idea of species? Does anyone know researchers that are working on Cretaceous corals and would be interested in this find?

I'm posting for a friend who purchased this "cidarid" from a collector that found it recently at a locality in the Weno formation (c. 98-99 mya) in Tarrant county, Texas. I'm thinking it's "Phyllacanthus" (and not "Stereocidaris") just going off pictures in books but I'd like some opinions from actual knowlegable people on which this is. "Phyllacanthus" and "Stereocidaris" are the two genuses most associated with the big cidarids around here but if there's other possibilities I'd like to know. Can someone list the easy-to-see differences between those two genuses?
