Annnnd... they're off and running!  (kind of) 

(Don't tell me we're going to get stuck at the Oligocene too)

 

Here's an Oligocene Rhynchobatus from North Carolina.

 

 

[Pleuromya]

This is a Procamelus tooth from the Miocene Bone Valley Formation of Florida.

Just 2 more and then we'll be stalled at the Precambrian again!

[FranzBernhard]

We are already stuck in the Pliocene since 4 weeks!

Ok then. Here's a Neptunea contraria from the Pliocene van Lilo Formation in Antwerp, Belgium.

 

 

And to keep things moving along, a Microcyphus sp. echinoid from the Egyptian Pleistocene at Hurghada.

Holocene. 

Tidgy, Testudo graeca graeca from Morocco. 

[Ludwigia]

I think I recognize my handwriting under Tidgy's right hand

OK, here's another Ediacaran/Vendian thing to start the next round (I don't think I've shown this in this topic yet):

Incertae sedis,

Yorga Fm,

White Sea Coast, Russia

 

[Isotelus2883]

For the Cambrian.

Eoredlichia intermedia

Yuanshan Mbr, Heilinpu Fm.

I'd be wary of wetting these Chengjiang fossils, they are soft and I wouldn't be surprised if some detail is washed away each time. That's too nice an example to lose!

[Isotelus2883]

It was isopropyl and I let it evaporate, but I'll keep that in mind next time. Thanks.

[Ludwigia]

Stictoporella cribrosa bryozoa (8x9cm.) from the Late Ordovician Katian Verulam Formation at the James Dick quarry in Gamebridge, On.

I think isopropanol should be pretty safe.  It evaporates quickly and isn't as problematic as acetone.

OK. I think some soft clayey specimens can puff up when damp (with water) but I don't know how they would be affected by different liquids.

[Isotelus2883]

Thanks for the advice.

[Isotelus2883]

It’s been a while.

Bumastus barriensis 

Rochester Sh.

Rochester, NY

Siurian

[Ludwigia]

Looks like we're back at it again. Here's part of a hash plate from the Devonian Givetian at Hungry Hollow Ontario with a few Tentaculites sp. along with a spine from a Platyceras gastropod and lots of crinoid and bryozoan bits.

 

[Baking Geologist]

Unidentified crinoid calyx from the Harrodsburg Formation Mississippian Bloomington Indiana 

[Ludwigia]

.

Lepidophyllum longifolium. From the Pennsylvanian (European Silesian) at Zbuch, Czech Republic.

Excellent specimen! I only found crushed partials when I lived in St. Louis....
