This 275-million-year-old animal had a twisted jaw like nothing alive today

Deep in a dried-up riverbed in Brazil, scientists uncovered a bizarre prehistoric mystery-twisted jawbones from a strange, long-lost animal unlike anything seen before. Dating back 275 million years, this creature, named Tanyka amnicola, belonged to an ancient lineage that should have already faded away, making it a kind of living fossil of its time.
