Hello again dear members! Last weekend I was exploring next to the sea in Santo Domingo, Dominican Republic and I founded this tubular rock with many little balls. Can somebody help me to identify this species?
Hi, @raymond-jaquez – To me this looks kind of like a fossilized tabulate coral. The little structures look kind of like zooxanthellae to me. I’m not an invert person, though. Perhaps @jkallmeyer, @kyle-hartshorn, or @bostickkw could help?
Not a member of Tabulata, they went extinct in the Permian (given you were in the DR, not a candidate). Not sure what it is from the pictures, but I wouldn’t rule out the possibility of it being a sponge fossil.
To me it just looks like a vug with secondary carbonates growing on the inside. Best of luck in identifying it.
@egardner to my knowledge there’s never really any fossils of zooxanthellae , unless you consider pigment biomarkers to be fossils. They’re too squishy-squishy and in the tissues of the polyps to be preserved as a body fossil. *shrugs
