Coral or sponge?
Hi guys!
I was in the Warsaw Geological Museum and there I came across this specimen which reminded me of Tabulate coral, but it was signed as a "sponge"... The sponge from the "maastrichtian age", when Tabulata already was extinct.
I couldn't be more confused. This one still looks like coral to me. What do you think?
Ok, it was in a museum and identified with the vague name Gabka (sponge). Most likely it is, but when dealing with this type of material, keep this in mind.
Coral Scleractinia Ahrdorffia Trauth, 1911. It looks like a Chaetetes type sponge but it is a coral.
It is also convenient to bear in mind that all the materials that are in museums are not always well identified. Especially when the identification is of the Gabka (sponge) type.
Signed: the devil's advocate.
