Dasha Posted February 4, 2022 Share Posted February 4, 2022 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? 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted February 4, 2022 Share Posted February 4, 2022 Hi, Dasha, and a very warm welcome to TFF from Morocco. I think sponge is probably correct. Lots of very varied species of sponge found in the European Maastrichtian. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Not always easy to distinguish at first sight. You may try googling for "Chaetetida" Our you my try this link: Chaetetids Franz Bernhard Link to comment Share on other sites More sharing options...
oyo Posted February 5, 2022 Share Posted February 5, 2022 (edited) 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. Edited February 5, 2022 by oyo 2 Link to comment Share on other sites More sharing options...
