POV: you went diving at night and spotted Ordovician nautiloids feasting on a eurypterid carcass, after a while the commotion has attracted the giants, Endoceratids slowly creeping into view

Some silly prehistoric guys based on creatures from the Palaeozoic Era 🦐‼️

They like to collect human objects and stash them in their secret gang hideout <:]

Here is a closer look at the members of the group:

I bought today from an lovely seller from an flea market in my Region. The half of tumbled gemstones and the tiny three ammonite.

The ammos selled for only each 50 cent 🥺 Wtf so cheap but small and cool. So i went with tiny finds for minimal storage. I appreciate it a lot.

Of course the other articel like the in half Quarz geodes 20€ or fist sized polished labradorite 25€ and ammonites each were at much higher in price to compare. With also some stonesalt crystal lamps.

To honest, i was looking for tumbled minerals like Heliotrope and or some sort of fluorite or malachite. But there was none of them.

Some ammonites, agate, some clear quarz like the smoke quarz, jasper Landschafts Jaspis the green gray with red spots, and the rutile quarz in golden and tourmaline.

Also the new polished Orthoceras fossil - Donnerkeil to wear like an talisman, but not for me.

Hello, i have an ask from the pics. Are these an Crinoid stem ?

These are little ones from the kids activity to dig and search sets from those Dinosaur parks / museum bags. Likely all shells & sponge right?

Hi! :D

So I'm gonna start by saying, I am most definitely an amateur, haha, so my word is not 100% certain, but,, I think I may have some news for you!

The segments in those pieces do resemble some Crinoid stems and columnals I've seen, but I've never seen a stem that varies in diameter like those. Yeah, it could be erosion, but the fact that it is all of them, the same precise, cone shape is a little suspicious!

But guess what else is segmented! Nautiloid shells! and guess who evolved straight shells quite a few times! Nautilods!! I believe what those are is Orthocones! (straight, long, shells of Nautiloid Cephalopods) (a squid-like animal, with a shell) They were around from late Cambrian to the late Triassic:) And in size, they range from less than 25 millimeters to over 5 meters!

Here is an example of an Orthocone!

looks pretty similar to yours, do you think?

That is so awesome, friend! Yeah, Crinoids are awesome too, but you definitely do have some of those in that polished egg (It's so pretty)

Also check out this huge one!

also yeah, the stuff from the museums and kits looks like shells and sponges to me, but again, im not a professional :) and I mostly know brachiopods haha

Thanks for showing me your cool fossils! They are lovely, I can imagine that joy you felt when you found them! Isn't fossil hunting the best thing ever!?! :) You're blog is inspiring me so post more of my fossils!

Oh, and if you want, give your Orthocones a little kiss for me! (I love to give my fossils a little peck, pretty cool to be able to kiss something that's millions of years old, right?)

An Endoceras orthocone descends upon an unsuspecting Pseudogygites trilobite. While they are often reconstructed swimming sideways, recent studies have shown orthocones actually swam upright in the water column, so I drew them more like a claw game, grabbing prey from the sea floor.

Drew a drawing of myself.

Ordivician cephalopods. The orthocones should probably be updated to be swimming vertically, but on the other hand the display is not tall enough for that.

Announcing Woodward Wednesdays

I have for a while wanted to post paleoart by the regrettably underappreciated early paleoartist, illustrator and a pioneer of females in paleoart, Alice B. Woodward. I originally planned a big post for International Women's Day, but my inability to keep on schedule scuttled those plans. To make up for that mistake, I'm announcing a recurring weekly theme: Woodward Wednesdays! I'll be sharing some select works by Alice Woodward that I've been trying to clean up and retouch from old scans of books, so they won't be quite on par with scanned or photographed originals, which if exist are behind paywalls. Hopefully they'll be some of the best freely available versions of her works anyway. As a taster of things to come, I want to kick things off with three rarely reproduced images from Evolution in the Past by Henry R. Knipe, from 1912.

This untitled illustration faces the title page, and is more symbolic than realistic, but showcases Woodward's talent more generally as an illustrator.

Titled "Silurian Marine Life" this piece almost feels like a still life, and simultaneously could be a neat little museum diorama. Also that orthocone is strangely adorable.

While it's Woodward's work on dinosaurs that most usually gets remembered in our time, she also illustrated both Paleozoic and Cenozoic life, perhaps more than Mesozoic taxa. This piece features Inostrancevia hunting pareiasaurs from the water, a highly dynamic scene the like of which I do not believe I've seen in paleoart either from this era or after.

some new evolutions in my paleo-themed fakemon dex!

Diggoroth (Ground type) and Thalasskoth (Ground/Water) are based on giant ground sloths (and in the case of the latter, aquatic giant ground sloths!) They are a split evolution from Slakoth.

Omaspire (Rock/Water) is an evolution of Omastar, based on orthocones.

You can read more about them in the zine.

Dawsonoceras is another cephalopod that swam the waters of Sillurian Gotland. They are an orthoceratid straight-shelled nautilid that floated in a vertical position on the water collumn.

Although they are far smaller than some of the other orthocones and endoceratids that reached lengths of up to 5 meters, their shell is just as beautiful to behold.

Kröger, B. (2013). The cephalopods of the Boda Limestone, Late Ordovician, of Dalarna, Sweden. European Journal of Taxonomy, (41).

Above specimens A,B, & E are dawsonoceratids, Scale bars: 10 mm.

From what I can gather, their adult shell diameter reaches 2.5 cm wide and it's hard to guess the total length because a lot of the shells are fragmentary. There seems to be one complete specimen online that was described to be 7.1" inches long

And another here that's 40 cm long, although it's an ID-guess from the blog poster

an orthocone/lava cone! it holds the two longest tentacles up on the shell to simulate flowing lava.
