Trip to the east coast of Denmarks mainland

[Phevo]

Figured I would post a short trip report from yesterday the 27-05-2017.

 

This trip went to the eastern coastline of Denmarks mainland, and the visible cliffs here consist of bryozoan chalk.

 

There is however a layer of roughly 500mm that is composed of cerithium chalk, which is my primary focus since it is here snails, ammonites, crabs, isopods and other fossils not preserved (or rarely) elsewhere reside.

 

During winter, alot of the hardened chalk and flint goes through a freeze-thaw process many times leaving the pieces split in half, often broken at the weakest point witch is usually were the fossils are.

 

During summer the opposite happens with thermal expansion, ultimately achieving the same result. 

 

Anyways here are some pictures of some of the finds

 

 

 

Odontaspis? 12mm

Bryozoan colony 70x80mm

 

unknown snail 19mm,possibly Metacerithium balticum which the layer is called after but the preservation is not good enough 

Leptomaria sp. 35mm

un-named snail 24mm

Eutrephoceras sp.? ca.50mm

Palaega danica 32x70 mm

I like the bryozoan - I'm used to seeing these from the Paleozoic so it's interesting to see younger examples.

What is the Palaega danica? Looks like a crustacean or isopod...?

Yes it's an isopod, on a close up the structure can clearly be seen

Very nice! I missed the mention of 'isopods' in your initial blurb. Lots of stuff in that formation.

"clearly"?  I cannot see anything.

Look at the unusual texture in the rock.  That is the critter's shell.  And yes, it is about the same color as the rock.  

 

Nice finds... my Danish friend gave me one of those isopods when I went to visit about ten years ago.  I imagine it is from the same place (I would have to go look mine up)
