A Temnodontosaurus sp. Ichthyosaurier vertebra probably from the middle of the spine. Found at the Late Aalenian, Achdorf Formation exposure at the clay pit in Geisingen, southern Germany.

 

You were too fast Ludwigia now my fossil is out of order

No worries. It's a nice tooth that you've posted. So I guess the Cretaceous is now next in line.

[JamieLynn]

whoa!! I managed to catch it on Cretaceous!! 

 

Trachyscaphites spiniger

Size 3 Inches  Ozan Formation

[FranzBernhard]

Missing the lower Cretaceous, I am smuggling in another upper Cretaceous . A little bit "old", but I have not shown it here on TFF, afaik. From field to polished slab, all done with angle grinder and by hand...

Here's another from the Upper Cretaceous, then. Just another Placenticeras.

 

Placenticeras meeki

Upper Campanian; Bearpaw formation

small and nice fly, coming from middle tertiaer (Oligocene) of Cereste in Southern France. Around 1 cm lenght

I think the Paleocene and Eocene got skipped. Here’s an unusual one from the Paleocene, Hologinglymostoma jaegeri from Couche 2a, Ben Idir Morocco.

An Eocene Dogfish, Squalus smithi, London Clay Isle of Sheppey UK.

How about a Wobbegong  tooth from the Miocene to get the timeline in order, Orectolobus sp Port Campbell Limestone, Portland Australia.

so, lets go to pliocene, Strombus coronatus, northern Italy

What a stunning specimen!

This one been reclassified. It is the housing tube for the acorn worm Oesia disjuncta and places Margaretia dorus as its junior synonym.

thank you @piranha

[piranha]

There is a small debate that has emerged in a recent paper. Foster et al. 2022 assigns a conditional synonymy and retains Margaretia for specimens that have an unoccupied tube. It will be interesting to see which method of classification will have more traction in any upcoming publications.

 

"Because these fossils show no indication of the enteropneust Oesia, found to be living inside tubes previously assigned to Margaretia in the Burgess Shale (Nanglu et al. 2016), we identify them as the tube structures Margaretia rather than the worm taxon itself."

a nice graptolite, Oktavites cf. spiralis, Eastern Germany (Grobsdorf, Harz), Ordovizium

approx. 6 cm wide plate

nice historic fossil

Oktavites is very funny, the name changes from Spirograptus to Monograptus and Oktavites, see Oktavites spiralis (fossiilid.info)

Maclurites sp. from the Late Ordovician Chatfieldian Farr Formation at Temiskaming, Ontario.

@rocket Ooops! Looks like great minds think alike and simultaneously
