Id Help For A Fossil In Phosphatic Preservation Of The Scandinavian Furongium

[krimfossil]

Hi Everyvone,

In Germany on the southern Baltic coast has a friend of mine

this fragment of an unknown fossil found. The rock is a pleistocene Geschiebe (Erratic boulder) from the Scandinavian Furongium. In the attachment there is a trilobite fauna of the genus Spaerophthalmus. The trilobites are living in the pelagic zone. The rock is called Stinkkalk (Stinkstone) or Orsten. Uncommon that a fossil is present in this size in phosphatic preservation. It phosphatized fossils have been described from the Stinkkalk. But these fossils are micro fossils.

The fossil fragment has a length of 1.1 cm.

My guess is that it is a Hyolith fragment. Other opinions are that it is a Conularie.

Perhaps there are fossils in North America as this fossil.

Somebody knows as a fossil?

Thanks for looking.

Best regards

Ronald

The trilobite hash is reminiscent of some facies of the ordovician of Pennsylvania. The highly ornamented fragment in question looks a bit like a fragment from a larger brachiopod or mollusc. I realize the pelagic zone doesn't have an abundance of these forms.
