KELUMAPUSAURA MACHI

LAGARTO CHAMAN DE LA TIERRA ROJA

Kelumapusaura fue un ornitópodo robusto de tamaño considerable en su etapa adulta, convirtiéndolo así en el hadrosáurido más grande de Latinoamérica descrito hasta el momento.

Contaban con mandíbulas fornidas terminadas en un pico ovalado con el que arrancarían la vegetación para luego masticarla con sus diminutos dientes que se alojaban uno apilado contra el otro.

Las patas delanteras recuerdan vagamente a las de los caballos actuales, ya que los dedos se encuentran dentro de un "guante" de piel que contaría con una almohadilla para resistir viajes largos, lo que apoya la idea del comportamiento migratorio de estos animales.

Así pues, se imagina que estos animales sostenían una vida comunitaria, con enormes manadas y una crianza atenta.

HABITÓ: Río Negro (Patagonia Argentina)

HACE: 73 a 69 millones de años (Cretácico)

ES UN: Ornitópodo, Hadrosáurido

MEDÍA: 9 m de largo x 4 m de altura

PESABA: unas 4 toneladas

COMIA: Herbívoro, plantas a altura media

Day 117 of DDD! The Kelumapusaura! A hadrosaur from Argentina who co existed with the famosu austroraptor! Multiple individual fossils have been found of this dinosaur thanks to a fossil bed.

#Hadvent Day 10

Kelumapusaura

As you may have noticed, I got a bit behind, and while I will go back and finish the ones I missed I thought it made sense to just skip ahead to the current prompts and try to keep up with those for the time being.

This one's definitely not my best work, the Austroraptor in particular could be a lot better, but I'm happy to at least have another sketch done. Looking forward to the next couple of pieces!

Artwork by Leonardo HerSan, written by @zygodactylus

Name Meaning: Reptile Shaman of the Red Earth 

Time: 73 to 69 million years ago (Campanian to Maastrichtian stages of the Late Cretaceous)

Location: Allen Formation, Patagonia, Argentina 

Kelumapusaura is another addition to the growing number of South American hadrosaurs, a radiation of this group that was previously considered unlikely but appears to have happened towards the very end of the Cretaceous period - thus showing that hadrosaurs reached almost every continent, except perhaps Australia! It was an average sized hadrosaur, reaching about 9 meters long, and as a member of the Kritosaurs it probably had enlarged nasal passages for sound production and communication. It would have lived in social groups, like other hadrosaurs. In the Allen Formation, Kelumapusaura lived in a coastal environment of fluvial plains, ephemeral lakes, tidal flats, and estuaries with extreme semiarid seasonality. Evaporites would accumulate in the arid seasons, only to be washed away as the wet season returned. Many dinosaurs are known from this formation: Aeolosaurus, Austroraptor, Bonapartesaurus, Bonapartenykus, Bonatitan, Lamarqueavis, Lapampasaurus, Limenavis, Menucocelsior, Niebla, Panamericansaurus, Patagopelta, Pellegrinisaurus, Quilmesaurus, Rocasaurus, and Willinakaqe. In addition, Kelumapusaura shared its home with pterosaurs such as Aerotitan, tuatarans, plesiosaurs, frogs, and a variety of mammals. 

Gobihadros mongoliensis

Artwork by KookaburraSurvivor, written by @zygodactylus

Name Meaning: Hadrosaur from the Gobi of Mongolia 

Time: 90 to 86 million years ago (Turonian to Coniacian stages of the Late Cretaceous)

Location: Upper Beds, Bayan Shireh Formation, Bayshin Tsav, Baynshire, Char Teeg, Khongil Tsav, Khoorai Tsav, Mongolia  Gobihadros is an early almost-hadrosaur from the Bayan Shireh Formation, one of the rare environments preserving the evolution of dinosaurs during the start of the Late Cretaceous epoch - essentially, when the charismatic dinosaurs of the Latest Cretaceous, such as hadrosaurs, first evolved. Multiple specimens are known from throughout the formation, making Gobihadros the best known early hadrosauroid from Asia. Adults reached sizes of about 7.5 meters long, and it had as many as three teeth per position within the lower jaw (this is high even for early hadrosaurs, more similar to those of later taxa, indicating convergent/parallel evolution). It also still retained the conical thumb claw of earlier ornithopods like Iguanodon. An older individual of the species showed signs of calcium pyrophosphate deposition disease, a condition of age causing restriction in the joints and pain during movement. Gobihadros lived in a semi-arid plain environment littered with lakes and rivers, with meandering bodies of water draining into the sea on the coast of China. Flowering plants were present in this environment, as well as a wide variety of animal life - sharks, Azhdarchids, turtles, and other dinosaurs like Alectrosaurus (probably), a troodontid, Erlikosaurus, Caenagnathoids, Garudimimus, Graciliceratops, a possible Carcharodontosaur (which would be a late surviving species), Talarurus, and potentially many more species waiting to be formally named.

Kelumapusaura machi Rozadilla et al., 2022 (new genus and species)

(Lower jaw bone [top, scale bars = 10 cm] and schematic skeletal [bottom] of Kelumapusaura machi, with preserved bones of type specimen in yellow, preserved bones of other specimens in white, and gray silhouette representing size of largest known individuals, from Rozadilla et al., 2022)

Meaning of name: Kelumapusaura = red earth lizard; machi = shaman of the Mapuche people

Age: Late Cretaceous (Maastrichtian)

Where found: Allen Formation, Río Negro, Argentina

How much is known: Parts of the skull, limbs, and vertebrae from several individuals.

Notes: Kelumapusaura was a hadrosaurid (duck-billed dinosaur). It can be distinguished from other hadrosaurids by several features, such as a lower jaw bone with prominent forward-pointing projections. It was probably closely related to several other hadrosaurids from the Late Cretaceous of South America, including Secernosaurus, Bonapartesaurus, and the also newly-named Huallasaurus. Kelumapusaura was large for a South American hadrosaurid, possibly reaching 8–9 m in total body length.
