Glossochelys is an extinct genus of sea turtles from the Pancheloniidae ^[1] that has been discovered in Eocene (Ypresian) deposits in Harwich, England (London Clay Formation) that was first described as a species of Lytoloma in 1842. ^[2] The type species, G. planimentum, was described as a separate species in 1871 by Harry Seeley. ^[3] It was possibly the same animal as Euclastes or Erquelinnesia . ^[4]
