Bienotherium

Bienotherium is an extinct genus of cynodonts from the Early Jurassic of China.[2] Despite its size, it is closely related to Lufengia, and is the largest tritylodont from the Lufeng Formation in China.[3]

Bienotherium is defined as being big and robust compared to other tritylodonts, and also by exposed maxillaries in the skull, an unusually long diastema and thin zygomatic bone.[3]

gollark: Um. What. The old IRC bridge?
gollark: Let's see if `kexec` works, since the BIOS on this server is awfully slow.
gollark: > An Validation is either a value of the type err or a, similar to Either. However, the Applicative instance for Validation accumulates errors using a Semigroup on err. In contrast, the Applicative for Either returns only the first error.> A consequence of this is that Validation has no Bind or Monad instance. This is because such an instance would violate the law that a Monad's ap must equal the Applicative's <*>
