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.

Fascinerend: Arizonasaurus was een verwant van de krokodillen uit het midden van het Trias, met een bijzonder zeil op zijn rug ... www.youtube.com/watch?v=HRN-...

Browsing Permo-Triassic fauna and deciding what jobs they would have in a Flintstones type situation

Atopodentatus - lawn mower
Lycosuchus - can opener
Arizonasaurus - notice board
Helveticosaurus - garbage disposal

For the longest time as a kid I thought Arizonasaurus was another spinosaurid. 😭

Arizonasaurus. Otro tío abuelo de los dinosaurios, este arcosaurio repite el invento del Dimetrodon: una lustrosa vela en la espalda. Y como el Dimetrodon, podría ser carne de "dinosaurización" para el ojo inexperto, incluso de "dimetrodonización", o ambas. Identificado por Sam P. Welles en 1947.

I may have mistaken the postosuchus for an allosaurus.
And the arizonasaurus for an outdated spinosaurus.
But what's the toy in the top-left? Looks vaguely spinosaurid.

Picked up an Arizonasaurus (probably meant to be Dimetrodon but it's scaly)

Sketch of Arizonasaurus, a bizzare reptile that looks alike to Dimetrodon.

Arizonasaurus, a sailed critter, one of the most interesting triassic crocs yet known, and with a wider head than its initial description reconstructed it as

And the northamerican species of Boverisuchus, a tall headed ziphodont eocene eusuchian with terrestrial affinities

Two 20-minute #paleostream sketches!!

Ozimek Volans and Arizonasaurus babbitti

Well, i don't even know where to start in this place haha, here's Arizonasaurus babbitti!, one of my favorite Pseudosuchians (croc-relatives) from the Triassic, we don't even know what was its sail for!

Almost thought the first one was Arizonasaurus.

In a broader polycule with Platyhistrix, Deinocheirus, and Arizonasaurus.

Every time I fold the wrappers I think of ctenosauriscids like Arizonasaurus

I told you I'd get to poposauroids
Day 14 of #Croctober and lets just take a moment to appreciate the absolute insanity that are derived poposauroids.
Throughout the Triassic this group brought forth forms with sailed backs, proto-theropods and more
