#nautiloide

Including this part of an limestone orthoceras/ orthocone fingertip size. An new piece. 🦑

Found an new rock with an orthoceras or alike specimen partial in it. Like an previous one.

The remaining fossil of the once chambers of the nautiloide marine animal, good to be seen on the red pebbles side, the mineralized white shell in red sandstone or Kalkstein. Now they are four cephalopod finds of Orthoceras by me.

They can be dated to 480 million years from the Ordovician, pretty cool and old preserved.

The same reddish brown colored rock like the other piece from last year, the first found.

Thinking my finds of them are an smaller species of the cone shaped cephalopods.

It’s called and also named here an Geradhorn from „ gerades Horn „ - linear horn form but my find is an half broken inner mineralization in the curved form in the rock. 😅

Really nice in the cool red limestone matrix, the other side has also an imprint of one or is the other side of the same on an curved surface.

New Fossil Friday for all!

To beginn, i put now the tiny snail / nautiloide fragments in this jar.

These are some of the recently new finds of, petriefied sponge fossils from the Aulaxinia sulcifera in flint.

Also the round Kieselschwamm.

This is an small sponge. I have recently and on previous rock search , parts of plenty of those seen around, but not picked up. Crap . <.<

Many of the round ones with holes or with stone chalk core in them are also sponge fossils in flint.

The mantle is chalk or gray black flint in variations.

We calls them Klappersteine sometimes.

If an intact on have an lose piece in the core of the inner mold, with the limestone or flint mantle, then when shaking it it may have an clapper click sound.
