Today's four random works of palaeoart:

Wayne Barlowe's Erlikosaurus, Mark Hallett's Euparkeria, Vasily Vatagin's Machairodus, and Tuomas Koivurinne's Rubeosaurus!
A scaly Erlikosaurus squats over a termite mound, lapping at a spire with a long, hot pink tongue. It has a skin pattern recalling that of a giant anteater crossed with a blue headed agama. In the background, a pair of Velociraptor stalk over a sandy dune. A Euparkeria with a rusty red hide with a cream underside and black speckles sprints bipedally in a wide-legged lizard-like fashion alongside a pond. Dense horsetails decorate the shore, fading into a wall of green. Two low-slung, long-tailed Machairodus cautiously approach each other with teeth bared in threatening postures. A group of spiky-frilled Rubeosaurus amble about an arid floodplain. A bolt of lightning splits the cloud-choked sky and strikes one of the ceratopsians directly atop its long nasal horn. The rest of the group reel in shock at the sight.

And here they are individually so I can get the written descriptions to fit in the alt-text.
Diatryma Aka: Hammerbill Origins: Agartha, Shangri-La Size: 2 meters tall Type: Bird Malleornis rudi is a large flightless bird descended from the same order as Gastornis. While an herbivore, subsisting primarily on fresh shoots, stems, fruits and nuts, it is incredibly territorial. This cantankerous disposition is similar to the infamous Cassowary of Australia and New Guinea, but this animal is much larger, often standing higher than a grown man and weighing in excess of 200 kilograms. Its strong legs and sturdy back make it a popular mount for the Vril of Agartha, but in Shangri-La the monks merely avoid them. Diatryma prefer dwelling in the dense bamboo forest in the center of the valley where there is plenty of fresh plant growth as well as ginkgo trees for fruits and nuts to eat. They nest on the ground like other flightless birds, laying 2-3 large speckled turquoise eggs which both parents guard fiercely from would-be plunderers. Once the fluffy and adorable chicks hatch, they will guard them till they reach a full meter in height and then abandon them. Sabertooth Aka: Saber-toothed tiger, Saber-toothed cat Origins: Agartha, Shangri-La Size: 3 meters long Type: Cat Sabertooths are the top predator of the Shangri-La valley, hunting a wide variety of the prey species endemic to the region. They are very large cats and are in fact a member of the genus Machairodus, the lineage that was thought to go extinct during the last ice age. Sheltered by the surrounding mountains, Sabertooths have been allowed to thrive here and have even migrated to Agartha via the subterranean network of caves and caverns deep below the mountains. While sharing the color scheme of the more well known tigers that prowl greater Asia (and coming in melanistic and leucistic variants as well), these powerful cats are more powerfully built, with large muscular forelimbs to help tackle prey to the ground and long serrated canines evolved to slice through the throats of pinned prey before they can struggle too long and cause the cat injury. Like most big cats, they are solitary, only coming together to mate. While fearsome, they aren't foolish, and will not hunt a healthy adult mammoth, instead preferring to hunt the injured or weakened members of the herds, though the vast majority of their diet consists of the endemic red deer and wild horses as well as the occasional chevrotain and Diatryma, with their only real competition being Tibetan Blue Bears. Mammoth Origins: Agartha, Shangri-La Size: 4.5 meters tall Type: Mammoth These giant proboscidians roam the grassy plains of the valley that circle the central bamboo forest, grazing in small herds of females and young, with the bulls being more solitary. This particular species is Mammuthus trogontherii, the Steppe Mammoth, which has long been considered the ancestor to the more famous Woolly Mammoth of the later Pleistocene. It seems this species accidentally escaped extinction inside the valley of Shangri-La where the vast surrounding mountains form a natural barrier from external threats. While the females are very protective of their young, not all make it to adulthood due to the local predators, the Sabertooths. As for their relationship with the monks, it seems to be an amicable one, with roaming herds often stopping by to receive offerings of food and water. On occasion, the monks have used mammoths to help move extremely heavy objects like stone blocks, which certainly helped them construct their massive temple in the past. While they are mostly peaceful animals, their space should be respected as they can be very dangerous if disturbed, much like any elephant. Yeti Aka: Abominable Snowman, Meh-teh Origins: Himalayan Mountains Size: 3 meters tall Type: Ape The Yeti, famous for its giant humanoid footprints it leaves in the snow in the Himalayan mountains, finds itself most at home here in the beautiful Shangri-La valley. They are large anthropoid apes, much taller than a human being, and covered in shaggy reddish-brown hair that turns gray or silver with age. They live in small family groups and are fairly passive beings that are content to eat bamboo, fruit, eggs, insects, and bone marrow they can scavenge from carrion. While predominantly peaceful, rabies is a potential threat, and rabid members are chased off outside of the protective mountain range with the help of the local Monks. These rabid yeti are the ones that are often seen and the source of the attacks on the locals and their livestock. The peaceful nature of the yeti has led to an amicable relationship with the local monks, who leave offerings of fruit for them. It is not uncommon to find yetis wandering about the temple and huts of the monks village and sometimes even sitting with the monks during prayer.

But the real stars of the predatory show in the Wastes are the several species of Machairodus cats. Here, two take down a Hipparion. They are rare to the east where Amphicyon (the bear-dogs) reign supreme. 5/7

This weeks #Lego #FossilFriday is #Homotherium

In 1826, Reverend John MacEnery found Pleistocene aged canine teeth in a cave near Devon.

In 1846, Richard Owen described those first fossils as Machairodus latidens,

In 1890, while reviewing the material, Emilio Fabrini proposed the name Homotherium, a subgenus of Machairodus.

Between 1918 and 1976 several more species of Homotherium were named

In 2014, a review recognized only one species of Homotherium in Eurasia, synonymizing the rest.

I saw a homotherium serum fossil today so, as soon as possible, I went to Wikipedia to find out why it was named that. It seemed peculiar. According to Wikipedia, there is no explanation.
The name Homotherium (Greek: ὁμός (homos, 'same') and θηρίον (therion, 'beast')) was proposed by Emilio Fabrini in 1890 during a review of machairodont material from the Late Pliocene-Early Pleistocene of Tuscany, Italy, without further explanation, for a new subgenus of Machairodus, whose main distinguishing feature was the presence of a large diastema (gap) between the two lower (inferior) premolars.

OH is the Machairodus design in When the Earth was Green based on Strata?

I had a feeling the behavior was but I'm just realizing she's also a woody brown with a pattern.

One interesting thing about these is that there's a lot of "fakes", or rather, using mammal teeth and slapping them onto Cretaceous matrix. Namely the surprisingly theropod-like canines of saber-toothed cats like Machairodus.

Though this does make me wonder if the first North American terror birds competed with Epicyon, Barbourofelis, Nimravides, Huracan and co. (they did compete with Machairodus, which was dominant at the end of the Miocene, before replacing it as the superpredator once it went extinct)

For real! @korybing.bsky.social did some of my favorite art for that chapter. It's a little focus on when plants do funny and fun things to our brains, set back in the days of Machairodus.

Hypotheses are still being tested but it seems sabertooths grappled prey and then delivered a kill bite to the neck or belly, largely avoiding bone. As they fed, they used their incisors to scrape flesh https://academic.oup.com/zoolinnean/article/188/1/319/5581941?login=false

Atticus’s stubby tail garnered him the title of “House Smilodon.” Poppy’s got too much tail for all that; maybe he’s the House Machairodus?

** Starships in my universe use giant cats and dogs to fend off alien monsters. Even after preventative tech improves, it remains standard to have at least one aboard for defense & companionship. That's all I'm gonna say about that, for now. 😁 (mostly based off Machairodus lahayishupup)

Me gustó mucho: mucha información bien explicada; de la que hay que pararse a leer y a pensar. Seguramente vuelva, e intentando apuntarme a alguna de las visitas guiadas; porque escuchamos de pasada las explicaciones de una, por coincidir en la sala y me pareció que lo contaban todo genial.
