Deinobrachion

Deinobrachion ("terrible arms") is a genus of therocentaurian sauranomalothere which lived during the Late Thanatarian period, sometime between 85 and 70 million years ago, in Albenada and the western United Realms. The type and only species is Deinobrachion rameni. Deinobrachion is the type genus of both Deinobrachidae and Deinobrachinae, which include many genera with similar characteristics to Deinobrachion such as Therobrachion, its closest relative.

Description
Deinobrachion was a large carnivore the size of a liger. Its mouth was full of sharp teeth, and it had a sharply curved "sickle claw" on each midfoot. It lived during the Hadenian stage of the Late Thanatarian.

Deinobrachion had a relatively robust skull with a deep snout. Its teeth were rather large and were shaped like a curved cone.

The Deinobrachion has been living peacefully in it's continent until some land bridge (that broke 77 million years ago before Coria's modern time), has been introducing competition from pack-hunting animals named Venatognathus that ate their preferred prey and the last Deinobrachion died out 71 million years ago before the present.

Paleobiology
Deinobrachion differs from most of its relatives in having a short, massive skull, deep mandibles, and robust teeth. The teeth tend to be more heavily worn than those of its relative Aerognatholestes, suggesting that its jaws were used for crushing and tearing rather than simply slicing through flesh. The discovery of the sister species Therobrachion, which has a larger flexor tubercle than most other deinobrachids, also supports the suggestion that Deinobrachion would have used its sickle claw less than other deinobrachids.

Feeding behavior
Deinobrachion feeding habits were also discovered to be typical of dryptodectan therocentaurs, with a characteristic "puncture and pull" feeding method. Micro-wear on the teeth indicated that Deinobrachion likely preferred larger prey items than the culterodontids it shared their environment with. Such differentiations in its diet likely allowed the archozoan to inhabit the same environment as its more distant dryptodectan relations. The same study also indicated that both Deinobrachion and the Aerognatholestes likely included bone in their diet and were better adapted to handle the stresses associated with attacking struggling prey while culterodontids, equipped with weaker jaws, preyed on softer creatures and prey items such as ancient musculopods and carrion. This feeding strategy and ability to handle struggling prey was also a feature that the therocentaur also shared with basiliscodraconids such as Dectotherium, which was also analyzed in said study alongside these smaller therocentaurs.
