Fossil Sponges From Russia

[Evgeny Kotelevsky]

Name: Sestrocladia sp.

Class: Hexactinellida

Age: K₂st

Location: Saratov, Russian Federation

A unique specimen, that once was damaged by storm, but continued living. It changed the dimension of growth and grew not additional roots (as usual) but additional stem!

Interesting specimen.

[Evgeny Kotelevsky]

Only once I had a luck to find a sponge with two stems (main stem is partly damaged). Have you ever found something similar?

Nothing like that. The only thing our sponges have are small, irregular root-like structures on the lower ends of few Heliospongia specimens.

Those structures are some kind of roots, because sponge needs something to anchor it at the bottom )))

Very nice specimen and a unusual growth pattern too! Thank you for sharing.

Very unusual looking ones.. I love sponge fossils.. I have never found any like those though.

I am afraid that I do not know what age (Age: K2st) is..

Cretaceous? If so what does the 2st mean?

Oh yes, welcome aboard..

Thanks for pictures!

C. lobatum is fantastic!

The 3d set of pictures is not Guettardiscyphia, they have no separate blades

Wow. Incredible detail. It looks like someone wrapped a paper towel around it.
