Linus Posted August 14, 2019 Share Posted August 14, 2019 I think this is a piece of a crab, perhaps the ”torso”? I found a paper with crabs from Kristianstad basin, but only images of claws, and it is not part of a claw from what I can tell? https://sp.lyellcollection.org/content/434/1/241 The crab in the paper is named Protocallianassa. What do you think? Link to comment Share on other sites More sharing options...

FossilDAWG Posted August 14, 2019 Share Posted August 14, 2019 For certain not a Protocallianassa. Don 2 Link to comment Share on other sites More sharing options...
Auspex Posted August 14, 2019 Share Posted August 14, 2019 The 'shell' appears to be sponge-bored, which might suggest mollusk. 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Spore-bored would mean it is of calcerous origin? It’s all calcerous here... The shell is very very thin. Thats why I was thinking in the line of crab.

Plax Posted August 14, 2019 Share Posted August 14, 2019 "shell" is possibly too thick for a crab but can also see the resemblance. Another possibility might be a very worn and broken echinoid. I can almost see the pores lining up on your specimen. 1 Link to comment Share on other sites More sharing options...

Another possibility might be a very worn and broken echinoid. I can almost see the pores lining up on your specimen. The images does not really show how thin it is. I upload another image that makes more justice to the thickness. Still I think they are thinner than this image shows. I noticed the ”spores” also. But the do not seem to have any holes in them. They more look like coloring? They are slightly elevated rather than indent? Link to comment Share on other sites More sharing options...

The callianassids have a poorly mineralized body that is rarely preserved, so the great majority of fossil species are known only from their claws.
