In 1846, Pierre Philippe Émile Matheron, a french geologist and paleontologist, described several large bones from Provence, France.[1] In the spring of 1869, Matheron formally described these remains, including a partial femur, fibula and possible tibia and a pair of associated caudal vertebrae, as the holotype specimen of a new taxon, Hypselosaurus priscus.[2][3] Among the bones, portions of the femur shaft are not preserved, along with a majority of the tibia, while both the fibula and vertebrae are entirely preserved.[2] The layer the fossils came from is likely from the late Late Cretaceous, specifically 70 million years ago.[4][5]

abstract	In 1846, Pierre Philippe Émile Matheron, a french geologist and paleontologist, described several large bones from Provence, France.[1] In the spring of 1869, Matheron formally described these remains, including a partial femur, fibula and possible tibia and a pair of associated caudal vertebrae, as the holotype specimen of a new taxon, Hypselosaurus priscus.[2][3] Among the bones, portions of the femur shaft are not preserved, along with a majority of the tibia, while both the fibula and vertebrae are entirely preserved.[2] The layer the fossils came from is likely from the late Late Cretaceous, specifically 70 million years ago.[4][5] Since its original description, several specimens have been referred to Hypselosaurus. One of these, originally described in 1957 by Albert de Lapparent, includes a caudal vertebra, as well as another vertebra described in 1960 by Bataller.[6] In 1993, a review of European sauropods stated that Hypselosaurus was a nomen dubium, and that its holotype could not be verifiably distinguished from other sauropods in the same, and many other, regions. Based on this, the material that was referred to Hypselosaurus by several other authors would have to be considered an intermediate titanosaur.[7] In addition to the holotype skeleton, Matheron described two fragments of a spherical or ellipsoid fossil in 1869. These fragments were studied for some time by Matheron and his contemporary french paleontologists, and the only probable conclusion was that they were fragments of eggshells. The eggs were proposed to have been significantly larger than those of Aepyornis when complete, and Matheron suggested that they either were a very large bird egg, or belonged to Hypselosaurus.[2] When originally named, Matheron proposed that Hypselosaurus was an aquatic crocodile, as was suggested by Richard Owen for taxa similar, like Pelorosaurus, Cetiosaurus, Streptospondylus and Steneosaurus. Matheron noted that the long bones, particularly the femur, lacked medullary bone, and thus proposed that it could not have been terrestrial like Iguanodon.
