Smalltooth stingray

provided by wikipedia EN

The smalltooth stingray (Dasyatis rudis) is an obscure species of stingray in the family Dasyatidae, found in the Gulf of Guinea. It is known only from a stuffed specimen described by Albert Günther in 1870, which has since been lost. In 1970, Springer and Collette assigned a jaw, tail, and two embryos from off Sierra Leone to this species, but later investigation found that the jaw belonged to a guitarfish, and the tail and embryos to a different species, possibly Dasyatis hastata.[1]
