Clovesuurdameredeor
Clovesuurdameredeor (meaning "sea creature of Closworth"; from the Medieval Latin "Clovesuurda" and the Old English "meredeor") is an extinct genus of machimosaurid teleosauroid from the Bathonian Cornbrash Formation of England. The type species, "C. stephani", was originally named ""Steneosaurus"" "stephani" by Hulke in 1867. Vignaud (1995) considered "S. stephani" to be a minor synonym of "Yvridiosuchus boutilieri" (then still in the genus "Steneosaurus"), but Johnson (2019) and Johnson et al. (2020) discovered that "S. stephani" was a basal machimosaur that was separate from "Yvridiosuchus", erecting the genus "Clovesuurdameredeor" for this.
