Love that Stockholm floors are often paved by these orthocone limestones some of which are huge!
And is that a trilobite I see before me?! ⚒️🧪

#MolluscMonday Rare example of an Ordovician orthocone nautiloid with a fractured shell. Photographed in the stone floor of the King’s Gallery at Hampton Court Palace last week.

A beautifully preserved straight-shelled cephalopod (orthocone) embedded in limestone.
I love having fossils in my hands and being able to touch them.

#SurvivingEarth ep 6 is a neat one.
That being said, first of all I'm just gonna say: The orthocone mating scene was really fucking touching in all the best ways.
But also they're portrayed with pinhole eyes so i think they were probably seeing it like the image on the right lmao... (1/?)

Thursday is collections day, so here are some lovely Devonian-Carboniferous cephalopods from the Michigan Basin: a pigmented orthocone nautiloid from the Traverse Gp., an encrusted orthocone from the Silica Fm., and a goniatite from the Marshall Fm.

#MolluskMonday ... Here we have densely packed phragmocones of late Ordovician orthocone nautiloids, a highlight of the Cincinnatian limestones. 🧪⚒️
One of my favorite field trip outcrops was a slab of nautiloid shells oriented parallel to wave ripples in the spillway at Caesar Creek.

Exhibit designers will see an orthocone and think "put that thing in an aquarium"

#MolluscMonday Photographed at Hampton Court Palace last week, orthocone nautiloids in paving slabs of Swedish Ordovician limestone. A microfault crosses the chambered phragmocone of one. The other fossil may represent a siphuncular structure but comments would be welcomed.

No new paleoart at the moment but I want to keep this account active so I thought I’d share one of my favorites so far! #paleoart #art #cameroceras #orthocone

My favorite Long Lad orthocone ( about a 5m long Endoceras giganteum I think) from Helsinki Natural History Museum

And whilst at Somerset House, it’s mandatory to check out the fantastic orthocones in the Öland Limestone paving! Orthocones are squid like creatures which had long, conical shells #urbangeology
