Ischigualastia, Chilesaurus and Changzhousaurus

I drew this piece simply because I wanted to properly say goodbye to TADC, a show that has been with me for the past 3 years.

Nanophoca vitulinoides was a small earless seal that lived during the mid-Miocene (~14-12 million years ago) in what is now Belgium, which at the time was covered by the southern margin of the North Sea.

It was slightly smaller than any modern pinnipeds, no more than 1m long (3'3"), and had more mobile front and back flippers than modern earless seals — indicating it had a different swimming style than its living relatives, and that it may have been more mobile on land.

It also had a very dense skeleton, which would have made it a slower, less maneuverable swimmer. It may have fed on small prey on the seafloor in shallow coastal waters, similar to modern bearded seals.

Here’s an assortment of dinosaur sketches I made, featuring various taxa such as the Abelisaur Ekrixinatosaurus, since I’m currently working on my upcoming animated short film and I don’t have any time to make any full drawings. What do you guys think about the colors and designs for any or each of the dinos?

Today’s echinoderm is Pseudocolochirus axiologus,commonly known as the Australian sea apple.

Uncharismatic Fact of the Day

Too many girlfriends? Not a problem for the hawkfish! The species in this family are protogynous, meaning that all individuals start out as females at birth. As adults, they form harems around a dominant male; but if there are too many females, then one or more of them will change into males and branch off with up to half of the remaining females. Not enough girlfriends? Not a problem either! If the number of females in a harem gets too low, or if they lose a challenge from another male, the former harem leader will simply revert back to being female.

Trotting through the open woodlands of southern North America is an animal belonging to a new kind of horned herbivore unique to the Americas, the Ten-horned Macallama (Hoplolama decaceras).

The Macallamas (Hoplolaminae) are a group of American camelids that can be found across North and Central America, with their most unique characteristic being their horns of all shapes, numbers and sizes that adorn their necks. These are used mainly for intraspecific combat, but can be just as effectively used for defence against predators. They are not bony horns like those of bovines however, but composed entirely of keratin, the same material as their hair.

The Ten-horned Macallama is a pretty good representative member for this group: It's a medium sized, generalist low browser common across its habitat. It lives in small mixed groups outside of the breeding season, keeping a collective eye out for predators. During said breeding season, they congregate so males can fight for the access to females.

Shikamaia akasakaensis was a giant bivalve that lived during the mid-Permian (~274-267 million years ago), in the shallow tropical waters of a carbonate platform atop an oceanic seamount in the region of what is now Japan.

It had a long flat shell up to about 1m (3'3") long, with a raised triangular hump at the front and wing-like flanges at the sides — a shape that helped to spread out its weight on the soft seafloor sediment.

Its shell was once thought to have been translucent, allowing it to host symbiotic photosynthetic algae inside its body tissues and providing it with the extra sustenance needed to grow to such a huge size. However, more recent studies suggest its shell was actually opaque to sunlight, so instead it may have hosted chemosynthetic bacteria similar to some modern clams.

…Or, considering that it shared its habitat with some other big invertebrates such as a large species of the marine snail Euconospira and a giant crinoid, Shikamaia could simply have been living in such an incredibly food-rich environment that it was able to attain gigantic sizes purely from normal filter-feeding.

Ok so had this sketch for awhile, ambuloceteus is quite a challenging one, have tried to go for a kind of scaled up otter/crocodile vibe

Kalakocetus aurorae was an early cetacean that lived during the Eocene, about 50-48 million years ago, in what is now the northwestern region of the Indian subcontinent.

It represents the (currently) most basal known branch of the whale lineage, with teeth that are transitional between the crushing herbivorous-omnivorous molars of the closely-related raoellids and the shearing carnivorous molars of later archaeocetes.

Only known from a lower jaw and teeth, its full life appearance is unknown — but based on the body proportions of other early cetaceans it would have been a roughly cat-sized animal, around 60cm long (~2'), possibly resembling a smaller version of its better-known relative Pakicetus. It was also probably similarly semiaquatic, wading into rivers to hunt fish and other small freshwater prey.

Lentamanusuchus hubeiensis was a small marine reptile that lived during the early Triassic, about 248 million years ago, in shallow tropical seas covering what is now southwestern China.

It was part of a group known as hupehsuchians, early cousins of ichthyosaurs that had toothless jaws, paddle-shaped limbs, eel-like tails, and distinctive bony armor along their backs.

Around 1.2m long (~4'), Lentamanusuchus had particularly broad flippers with extra bones in its hands, a transitional state between its ancestors and later polydactylous hupehsuchians.

Although ceratopsian dinosaurs were widespread around the northern continents during the Cretaceous, for a long time they appeared to have been completely absent from Europe. A few possible fragments were found – but their identification as ceratopsians was highly disputed, with some paleontologists instead identifying the remains as belonging to ornithopods.

But this year some new fossils have given more support to the ceratopsian interpretation, suggesting that a whole diverse European branch of these dinosaurs was there the whole time. They'd just been misidentified as rhabdodontids due to the convergent anatomy of their teeth, jaws, and limbs.

One of these newly-recognized ceratopsians was Ferenceratops shqiperorum (previously known as Zalmoxes shqiperorum), which lived during the late Cretaceous (~72-66 million years ago) on the subtropical Hațeg Island, in the region of what is now Romania.

It was a small species, about 2m long (6'6"), and seems to have lacked the elaborate frills and horns seen in many other ceratopsians, despite being closely related to both protoceratopsids and stem-ceratopsids.

Its new genus name references Ferenc, the birth name of Baron Franz Nopcsa, the gay Transylvanian paleobiologist-adventurer-spy who originally found some of its fossil remains.
