Lone Hunter Posted April 7 Share Posted April 7 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 April 7 Share Posted April 7 Yup, you nailed it. This is a a rugose coral. Link to post Share on other sites

oyo Posted April 7 Share Posted April 7 (edited) If it´s Cretaceous it´s not a rugose coral. Edited April 7 by oyo Link to post Share on other sites
LabRatKing Posted April 8 Share Posted April 8 6 hours ago, oyo said: If it´s Cretaceous it´s not a rugose coral. Why would it be cretaceous? 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 April 8 Author Share Posted April 8 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

Lone Hunter Posted April 8 Author Share Posted April 8 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 April 8 Share Posted April 8 (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 April 8 Author Share Posted April 8 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
oyo Posted April 8 Share Posted April 8 Hace 8 horas, FranzBernhard dijo: @LabRatKing, @oyo, Así que permite hablar el espécimen por sí mismo: ¿Qué opinas, rugosa o scleractiniana? ¿Qué es la de la película, pero ¿podemos decidir realmente por este tipo de fuera de la cuencia? 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
