The preservation of the 3D structure is incredible!

The coolest fossil I've ever seen:

Really cool :)

I saw another commenter saying something about fossilised dragon tongue? :P
There are actually fossils made of gemstones!
A pliosaur specimen (nicknamed "Eric") was found in Australia, and it's made of opal.

Tonight’s flocking #Paleostream sketches: Vesperopterylus dangling, American Mastodon browsing, a bust of Umoonasaurus, and silly Dsungaripterus. #paleoart
Four black-and-white pencil sketches of prehistoric animals on a piece of paper. In the top left is a Vesperopterylus dangling from a thin branch by one hind foot, in the top right is an American Mastodon walking away from the viewer through a shadowy cypress swamp, in the bottom left is a side-view bust of Umoonasaurus, and in the bottom right is a small and stylized Dsungaripterus in an excited T-pose.

Here's what I did for #Paleostream with Vesperopterylus, the American Mastodon (Mammut americanum), and Umoonasaurus.

#paleoart #sciart #art
Vesperopterylus, a derived anurognathid pterosaur from the early Cretaceous, looking at the camera while it's on a tree branch. American Mastodon sketch, based on a photo I took at the Burke Museum of Natural History in Washington state. Wish I had more time for the proportions but oh well. The early Cretaceous plesiosaur, Umoonasaurus, giving birth to a little shitlet baby.

Later that year he donated it to the Australian Museums.

In September 1988, it was prepared by the Australian Museum.

In 2006, Benjamin Kear and colleagues named Umoonasaurus, part of Pliosauroidea and the most basal Rhomaleosauridae.

This weeks #Lego #FossilFriday is #Umoonasaurus

In 1987 an opal miner in Coober Pedy found an opalised fossil. They were part of the Zorba Extension Opal Field.

In 1988, the chairman of the company Comrealty ("Mr. Sid Londish") bought the specimen.

For those that missed the streams, here is the end result of building the Temu fossil building blocks out of lego.
The only one I didnt name was the front now, second from the left. The one with the insane wings. Open to suggestions for what its meant to be as i have no idea.
Back row, from left to right, we have Cuvieronius, Ojoceratops, Arizonasaurus, Zhejingopterus Middle row, from left to right, we have Craterosaurus, Dilophosaurus, Umoonasaurus, Mononykus Front row we have Europasaurus, not-a-clue-asaurus, Polyptychodon, Saichania...

A digital drawing of a Vesperopterylus. It looks too much like Anuragnathus though. A digital drawing of an American Mastodon. It’s legs are too long and thin. A digital drawing of Umoonasaurus. A digital drawing of Dsungaripterus flying through the sunsetting sky.

My favorite instance of this was when a majority of a plesiosaur skeleton was found opalized in Australia. All the photos I can search of it are relatively dull, but I bet it's even better in-person.

Opalised skeleton of Umoonasaurus demoscyllus displayed in the Australian Museum, Sydney. #FossilFriday #MuseumCore
A fossil skeleton of a small plesiosaur, preserved in white opal. Almost the entire skeleton is present, although most of the tiny paddle bones are missing.

Today's aesthetic for #FossilFriday is more beautiful in death.
The opalized fossil skeleton of "Eric" the pliosaur (AKA the Crystal Sea Dragon) Eric is the holotype of the Umoonasaurus genus, and parts of his fossilized skeleton gradually turned into opal over the millennia-long process. He is currently in the custody the Australian Museum. pyritized ammonite cluster One looks like a golden ram's horn, and while there's no evidence to suggest fossils like these influenced the myth of the golden fleece, it is a stimulating prospect to consider. a scorpion forever sealed in polished amber, which is fossilized tree resin Naturally polished Petoskey stones, which are pebble-shaped fossilized rugose coral, Hexagonaria percarinata
