incredible, I love the early insects...

digged many years ago in a great quarry in northern germany (Hagen-Vorhalle) for a museum looking for carboniferous insects. We did not find many, but each one was a great moment...

Nice!

 

Did you pick through spoil at the site, or back at the house to find the forams?

nice hugh block with many many shells and snails from famous closed pit in Weitendorf / Austria. Pliocene

Size: 35 x 20 cm, as they are fragile it is not easy to get a block like this complete

the one on the right side (at the arrow) shows color-pattens

Mix of both

[Missourian]

Bison mandible

Bison sp.

Kansas River alluvium, Pleistocene

Wyandotte County, Kansas, USA

 

[JamieLynn]

@rocket - was that supposed to be Paleocene rather than Pliocene? We completely skipped  Eocene Oligocene Miocene and Pliocene

[rocket]

sorry, you are right, was too fast...

so I add a precambrian one, Ediacarian, from the classic locality in Australia, Ediacara...

no fossil on it, but it comes from there!

Weitendorf, Styria, Austria is shallow marine Miocene, more precisely, Langhian.

never heard, what is Tafoni?

[marguy]

The term “taffoni” or “tafoni” comes from the Corsican “tafone”. It designates a rounded cavity whose dimensions vary from a decimeter to several meters in depth and diameter. These cavities are formed by the erosion of grainy magmatic rocks such as granite and sandstone sedimentary rocks.

So @FranzBernhard or @MeargleSchmeargl - where are we in the timeline? There was some confusion earlier.

Indeed! 

Lets start over with the Cambrian!

OK, here we go... Small trilobite that we've probably seen before but here is my example:

Arthricocephalus sp, about 7mm long

Lower Cambrian Stage 4/Duyunian (Upper Botomian)

Dachenling Fm?

Guizhou? China

As you can see, I'm not all that sure about this info, so I'd appreciate hearing from anyone who knows better.

Beautiful! I have 3 small jaw sections myself, but you've got some great variety, a thread has to be made now for us Richard Spur enthusiasts!
