Trinisaura

“ The presence of axially elongate distal caudal vertebrae, pubis with long prepubic and postpubic processes, as well as a femur with a distinct anterior trochanter, a pendant 4th trochanter, and a shallow anterior intercondylar groove constitute a combination of characters present in the Late Cretaceous Patagonian. ”

Trinisaura santamartaensis is an extinct genus and species of ornithopod dinosaur known from the lower levels of the Late Cretaceous Snow Hill Island Formation (early Maastrichtian stage) of James Ross Island, Antarctica.

Etymology

The genus name is to commemorate the efforts of Argentine geologist Trinidad "Trini" Diaz and the Greek root -sauros, meaning "lizard". The species name is after Santa Marta Cove, where the fossils were collected.

Physical Appearance

Trinisaura is a small ornithopod with long tail and tail quills, short, thick fur on hands, knees, neck, and near the tail, as well as long hind limbs and digitigrade, an oval-shaped head, and a short, smooth beak. The only few ornithischians found in Antarctica are related to Hypsilophodon foxii rather than Morrosaurus antarcticus, another relative.

Abilities

Trinisaura santamartaensis was immune to cold temperatures in a temperate forest in the Cretaceous period, as any reason for this biome was a continental biome with taiga remixed, allowing Trinisaura to have furs like an ecological niche as tortoise to ptarmigans altogether. Trinisaura may have quills on its tail, like Morrosaurus antarcticus, for self-defense.

Ecology

Trinisaura is also noted to have a slower growth rate than genera that lived in warmer climates, an adaptation to the colder temperatures of the Antarctic. Trinisaura is known solely from the Gamma Member of the Snow Hill Island Formation on James Ross Island, an island in the James Ross Island group on the northeastern edge of the Antarctic Peninsula. The Snow Hill Island Formation is one of only two major dinosaur-bearing rock formations found on Antarctica, bearing all but two of the continent's named dinosaurs.


This is due to the two taphonomic and depositional settings of the Snow Hill Island Formation, with Trinisaura found alongside other dinosaurs with little to no signs of scavenging; Trinisaura itself is clean of scavenging.

Behavior

Shy.

Distribution and Habitat

Trinisaura was lived during the late Campanian stage of the Upper Cretaceous, around 73 to 72 million years ago in what is now James Ross Island off the coast of northern Antarctica near Patagonia, which is taiga forests to tundra.

Lore

When a Trinisaura hatches from an egg, it is instantly domesticated because the survivor always lives within 19 radii of the hatching egg and consumes grasses, seeds, flowers, and roots. You can feed an adult Trinisaura grasses, seeds, blossoms, and roots if it isn't already taught.
