Glyphis hastalis is a dubious species of extinct river shark from the Early Eocene of England. Fossil teeth have been identified from the London Clay.[1][2][3] The type specimens are two isolated teeth that resemble the lower teeth of the modern speartooth shark.[4] It is the type species of the genus Glyphis, represented by modern relatives such as the Ganges shark and speartooth shark.[4][5] However, other authorities have found that its classification into the genus Glyphis is likely erroneous.[6]
