Had a nice day out with the Scarborough Rotunda Geology group. There were multiple whale pods and many seals in the bay. Had a good look at the Jet Rock and discussed deep water fine clastic deposition. #Geology #Paleontology

Okay the really wonky grammar is bothering me a lot.

Giant orthocones (a type of cephalopod that lived 460 million years ago) were, at the time, the LARGEST animals on Earth at a top predator in the ocean.

From tentacle tip to cone tip, they were 11 meters (36 feet) long.

that orthocone looks like it's been caught in the middle of something quite embarrassing...

Today's four random pieces of palaeoart:

Robert Cremin's Tyrannosaurus and Corythosaurus, William Scheele's orthocone, Sano Kuzuhiko's Apatosaurus, and Wouter Verhesen's Carinodens!

For the flagship, probably something like a phoenix, whether it’s a Bird Wyvern or an Elder/Demi-Elder like people are speculating

If we get a new Cephalopod, I’m thinking either an invader or like a flying squid in the Skybound Eyrie; a friend and I thought about maybe like a rocket orthocone

An endocerid cephalopod from the Ordovician. Like other endocerids, it was much closer related to the nautilus than to squid or octopus. It was an orthocone meaning its shell was straight and pointed.

A few highlights of "Library of Life." Some of the first fossils in the collection: orthocone nautiloids from Douglass Houghton's surveys of Michigan in the late 1830s and early 1840s.

anyway im tired of primary discourse, so here's every surviving earth episode ranked
8. When the Oceans Shrank. the orthocone scene is beautiful but this one doesnt offer much to me, and the epilogue was by far the most lackluster of all of them

Favourite dinosaur: all the sauropods.

Favourite prehistoric mega fauna: giant orthocones

Hope you make it back! If you do, the Manitoba Legislative Building is a free fossil hunt — its Tyndall stone walls are packed with orthocone nautiloids and corals from that same Ordovician sea. A museum you can walk through without a ticket.

Well the full answer is 'yes if the Orthocone in question is featured in a Chris Packham docu, otherwise most likely no'.

'That is the biggest predator that the world has seen up until this time.'
Endoceras, the Giant Orthocone.

One issue is the lack of a species' proper name, instead of just things like "Orthocone" and "sea scorpion." At least the jawless fish Sacabambaspis had its name said. 🤓🦕🦖

Also got some lovely carboniferous #Crinoids #bryozoans and orthocone #Nautiloids too. #geology #paleontology #fossilfriday

The 'after' scene is good; loved the scorpions and especially Protoaxites, as well as the indication that fire is about to make its grand appearance on Earth.

The fundamental narrative issue prevents me from giving this a score as high as I want to, but the orthocone scene is so fucking cool. 7/10.

Here, it only comes in at the very last moment. An iceberg rolls in, freshwater kills things. This is said to be localized; the sea level drop is global. But the impact is never shown. No bleached reefs until the end. The orthocone lays her eggs, and we see nothing else of her trying to survive.

I do dislike the fact that the Sacabampaspis just randomly gets to mate as the last one as a random female bumbles in. It feels a bit convenient and contrived. I'd much rather the time be spent on watching the orthocone lay her eggs.

As a bonus, the reef spawning scene had great music!!! Love that

#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/?)
