Scientific figure showing the skull of the protocetid whale Protocetus atavus and the newly published endocranial cast; the endocast is shaped like a flattened Hershey's kiss, with a long olfactory tract and well-developed olfactory bulbs.

#whalewednesday Endocranial anatomy of the OG protocetid whale, Protocetus atavus - protocetids had surprisingly large brains, indicating brain expansion occurred early in cetacean evolution; also retained well-developed olfactory bulbs (and smell). 🐬🧪🦖Read here: academic.oup.com/evolut/advan...

Regarding the sense of smell, we basically found that no part of the olfactory apparatus was significantly reduced, indicating that these amphibious cetaceans most likely had a good nose (likely much better than ours), and that the reduction of this sense most likely came later in their evolution.

Comparing the relative volume of the brain endocast, we found that this early whale was quite brainy, which is a surprise, as the first cetaceans with big brains were so far understood to be the fully aquatic basilosaurids.

We addressed two aspects of cetacean evolution: their acquisition of a relatively big brain and the evolution of their sense of smell. As other mammals secondarily adapted to the aquatic environment, cetaceans have been assumed to reduce their sense of smell (which is air-born in this group).

We ct-scanned the skull of Protocetus atavus, an amphibious cetacean coming from the Mokattam Formation in Egypt. The inner anatomy of the skull was reconstructed, and we were able to reconstruct the brain imprint (endocast) as well as the different components of the nasal cavity.

Named after the cat-headed goddess Bastet, Bastetodon is symbolically linked to Sekhmetops, inspired by the lion-headed goddess Sekhmet. Mythology meets science in this incredible find! #SallamLab #MUVP

Thank you @gohar.bsky.social for a very nice invited talk on whale evolution for our group in Oslo yesterday!🐳🐋🐬

As usual, one of the best reconstructions of a protocetid early whale!

Oh groovy, our paper on the hindlimb biomechanics of the Triassic dinosauriform Lagosuchus is out! A quick thread for now. We uCT-scanned most of the existing skeletal material for this important outgroup to Dinosauria. We sorted through the elements and chose the best ones to make a 3D model from.

You did a great job!

My initial sketches, transferring the anatomy of different modern animals onto the skull to see what felt plausible.

The reconstruction I settled on, taking cues from moose and camels along with my own previous drawings of other protocetids.

Some sketches exploring the reconstruction I’ve settled on. You know you love an animal when you’re willing to absolutely roast it.

Full painting of Makaracetus based on my earlier research and design work. This actually started as a screenshot of a swimming moose from Planet Zoo, which I warped and painted over in Procreate.

#FossilFriday with its bizarre skull, the protocetid whale Makaracetus has become my beloved nemesis. It’s extremely hard to reconstruct, but @gohar.bsky.social recently told me that my illustration of it is the most accurate he’s seen, so I must be on the right track. #paleoart #sciart #whale

An Ancient Whale Named for King Tut, but Moby-Dinky in Size Paleontologists in Egypt announced the discovery of Tutcetus rayanensis, an eight-foot-long leviathan that lived 41 million years ago.

I was searching for information about odontolite, which I did not find, but this fascinating article about early whales popped up instead. And now I need you all to learn about Tutcetus rayanensis and the Valley of the Whales. 🐳 (gift link)

Phylogenetic tree of cetaceans, including Tutcetus, taken from Antar et al 2023

Described only a week after the most massive basilosaurid, Tutcetus is not only one of the very smallest, with an estimated body length of only about 2.5m, but one of the earliest, coexisting with protocetes in the shallow coasts of Egypt during the early middle Eocene.

Tutcetus rayanensis,

New genus and species of ancient basilosaurid whales just discovered!

It's 41 million years old and comes from Egypt!

@AFP: Egypt dig unearths whale that lived 41 million years ago when the species was just completing their move from land to sea.

The team has dubbed the species "Tutcetus rayanensis" after the Egyptian boy king Tutankhamun and the Wadi El-Rayan Protected Area

A visualisation of how the extinct basilosaurid whale, Tutcetus rayanensis, might have looked 41m years ago on a good joyful day. Mouth open. Smiling.

They really looked at the newly discovered mini whale and decided “I’m gonna render it as the happiest whale ever.”

Meet Tutcetus rayanensis,
a fossil whale discovered in a middle Eocene (41 mya) formation in Egypt.

"This new whale is the smallest basilosaurid whale known to date...of that family from Africa."

Digital painting of Tutcetus near the surface of the water. It's shown from the side, facing right, and positioned diagonally, with the tail higher than the head. It has two pairs of flippers: the back ones are tiny, and the front ones look more like those of manatees than those of the modern whales. The whale also has a tiny, barely there dorsal fin. There are light shafts piercing the water, some behind and others in front of the whale.

The newly described Tutcetus. In stark contrast to the *also* newly described Perucetus, this guy has the distinction of being the smallest basilosaurid ever discovered. It's a good time to be an ancient whale enjoyer.
