Some work out recently made, cetotherium riabinini is a small baleen whale from the Late Miocene of the Eastern Paratethys sea (Ukraine), a almost complete individual show it had remarkable body proportions unlike modern elongated species in a minuscule size.

I should say that this Monday finally after a year waiting I got a new laptop, though I have yet to settle some things before taking it, I started to prove it to see how well it runs, so far painting has improved, here is a funny cow as a first try

Hey sorry for being inactive in these week, life has been harsh and I really do not have any energy to post as I wanted, so in the meantime here is a sketch of Arctodus simus and Ursus maritimus, two bears that probably interacted with each other on north American through the pleistocene

I made this for twitter as I restored the account I was willing to terminate, but it came along a lot of things while I was doing this that ended up being more of a comment regarding my own feelings on the current events, a way of telling myself and others that there is hope, that there can be hope.

It was a good run as it lasted but I decided finally to deactivate my account, it worthless trying to engage there not even in the basic level of scroll for your favorite stuff or curate your own feed, I hope others can tolerate better if it doesn't derail more but I'm tired entirely of the shithole

Andrewsarchus once though to have been a mesonychid of large size, it passed through varied cladistic revisions that changed radically the way it was reconstructed, now it is the only member of its own family, Andrewsarchidae most close relative to entelodonts.

For reference the base of the body illustration of Embolotherium is based from Aktautitan as we lack proper postcranial material of this large brontothere, I thank @triloboii.bsky.social for have made this chart some time ago that exemplify the varied range of this genus in size.

The late Eocene of Mongolia received the culmination of more than 20 million years of a trend mammalian gigantism after the KPg, which brontotheres specialized becoming some of the largest land mammals on earth with species like Embolotherium andrewsi reaching the height an Asian Elephant.

Hesperotherium is among the youngest chalicotheres in the fossil record, although it's only known by few jaw pieces and teeth, comparing to other chalicotheres like Nestoritherium it likely could have had a short muzzle, if they had the usual late chalicothere body form is just speculative.

Allosaurs and megalosaurs are among the best recognized macropredators in the Jurassic, but there were also metriacanthosaurids, which on Asia they were pair in size to those other theropods with the 10 meter long Yangchuanosaurus, a peculiar looking theropod from that period.

The funny "Whale Killer" gang from the late Eocene: Basilosarus king of the sea, along Embolotherium and Andrewsarchus, which the later had a total makeup since its original Mesonychid shape into this form as close relatives of Cetancodontamorphs such as entelodonts.

The American lobster is among the largest as well the heaviest of living arthropods with specimens record of about 20 kg, with a body length of more than 60 cm, excluding their massive claws; unfortunately overfishing has caused the decimation of these giants making them barely as big as before.

I think I will never stop to get amaze by the existence of gorillas, almost monumental forest apes that reach titanic sizes of any living primate, and eastern gorillas take the title of largest living primate with record specimens reaching up almost 2 m upright.

Fadenia represent one of the best preserved species of Eugeneodont caseodontid, a lineage of middle to late Paleozoic holocephali, living around the end of the Permian and managed to survive briefly into the Early triassic.

Well as Bluesky is finally public I wanna try posting now that is likely it will be shared outside, the funny paleozoic eugeneodontids, Fadenia, Ornithoprion, Caseodus and Romerodus, each species are among the most complete in body material

This is a way I do work with feathered animals before adding up the plumage, really got often hard to figure out how to position feathers in large animals so I do inverse work, sort to help also to get the anatomy right

I think that I should start posting some of my stuff that is on the other twitter account to fill up.
The african Giraffatitan brancai is among one of the most complete large sauropod species we have remains of, so well preserved we can properly calculate its body mass with accuracy.
