#Paleostream 25/04/2026

his week's #Paleostream flocking was themed around the Walking With series of palaeontology documentaries to honour the last Ben Bartlett who passed yesterday

we sketched Ornithocheirus, Brontoscorpio, Liopleurodon, and Koolasuchus

Prionosuchus

Prionosuchus is a genus from the early Permian period of Brazil and is a very large temnospondyl with estimates of it growing 6-9 meters long!

These estimates are based on skull length, with one skull measuring over a meter in length alone

Eryops megacephalus

Large (2-3 m / 4-7 ft | ~225 kg / ~500 lb) amphibious temnospondyls from the late Carboniferous to early Permian. They are named after their rather large and elongated head which housed numerous teeth. Some skin impressions show that they had ovoid bumps/scales running down the body.

temnospondyl: permian panic

Eryops megacephalus

An amphibious temnospondyls from the early Permian deposits of the Texas Red Beds. Eryops averaged a little over 2.0 m (6 ft 7 in) long and could grow up to 3 m (9 ft 10 in), making them among the largest land animals of their time.

Onchiodon 

An extinct genus of temnospondyl. It is primarily known from the Carboniferous and Permian of Europe, but also from the Permian of North America. It was an amphibious carnivore.

Platyoposaurus stuckenbergi

A temnospondyl from Permian Russia. It had an estimated length of about 2.5 m. and had a long snout that looked like a crocodile.

Prionosuchus plummeri

A temnospondyl from early Permian Brazil. Most specimens have been estimated to be about‭ ‬2 to 2.5‭ ‬meters long.‭ ‬ One excpetionally large skull however had a length of about‭ ‬1.6‭ ‬meters,‭ ‬suggesting that this individual had a total body length of about‭ ‬7.5 ‬meters.

On yesterdays stream we covered the Tiki formation of India, a productive Triassic formation most notable in recent years for it's bonebed of Colossosuchus. This formation was deposited largely during the Carnian, an episode in Earth history known for increased global rainfall.

Subsequently there are lots of flooding events from this period and since we have this from the Tiki formation as well a flooded forest seemed like the best setting for this piece. Also not the baby and juvenile Colossosuchus: the bonebed that preserved them mostly consisted of...

...younger animals so we though if could be cool to show a nursery. Interestingly phytosaurs differ from crocodile in that they have proportionally much shorter snouts as babies. Besides this charismatic megafauna we have a lot of small stuff from here. Based on micro...

fossils the most common animals should actually be small archosaurs, but so far their record isn't good enough to put a name on them. Plants are also known in larger quantities.

Thankfully Julianne Kiely helped with this and even provided a quick little guide to the flora of this formation.

As so often Discord member JW provided the size charts for this stream. take note on the huge temnospondyl from here, a specimen that is now unfortunately lost. Thanks to personal communication with Dr. Sanjukta Chakravorti we were able to get a pretty good estimate.
