Lone Hunter Posted Wednesday at 03:56 PM Share Posted Wednesday at 03:56 PM I have zero experience with corals, so just going by pictures I've seen on this guess. This was in creek with Alluvium/ Eagle Ford mix, I spent about an hour prepping it to expose the top and smooth side of what was a mound with vague outline. Hope I didn't screw it up too much!

LabRatKing Posted Wednesday at 06:22 PM Share Posted Wednesday at 06:22 PM Yup, you nailed it. This is a a rugose coral. Link to post Share on other sites

oyo Posted Wednesday at 07:24 PM Share Posted Wednesday at 07:24 PM (edited) If it´s Cretaceous it´s not a rugose coral. Edited Wednesday at 07:25 PM by oyo Link to post Share on other sites

Given this is an alluvium find, there is no way to determine age, or even source. However morphology is consistent with a rugose coral. Link to post Share on other sites
Lone Hunter Posted Thursday at 04:40 AM Author Share Posted Thursday at 04:40 AM I am always finding things that don't belong in this area for the reason stated above, in addition there is a lot of fill/erosion control rocks mixed in as I have learned. Also have things collected from area in the Trinity river flood plain near Lone Star park thats mixed in. Makes it more difficult to learn and ID things for sure. Link to post Share on other sites

If it's rugose coral it's not cretaceous. Do you like it better like this? Link to post Share on other sites
Lone Hunter Posted Thursday at 06:48 AM Author Share Posted Thursday at 06:48 AM I see how that was confusing in the tags, I was just referring to the the age of this area, which does not always match up with what the creeks and such bring. Link to post Share on other sites
FranzBernhard Posted Thursday at 07:15 AM Share Posted Thursday at 07:15 AM (edited) @LabRatKing, @oyo, so lets speak the specimen for itself: What do you think, rugosa or scleractinian? From the texbook, the differences should be clear, but can we really decide for this out-of-context specimen? I can not decide...

Lone Hunter Posted Thursday at 07:54 AM Author Share Posted Thursday at 07:54 AM Would the appearance of the 'button' in the middle (plate?) make it rugosa? Link to post Share on other sites

That is the nature of alluvium- stuff washed down by a river. Plus, as you say we humans move a lot of rock around. Link to post Share on other sites

No puedo decidir... Franz Bernhard Oh no, I don't know. If cretaceous must be Scleractinia but if no sure stratigraphy ....... pssss. 1 Link to post Share on other sites
