Alcide Charles Victor Marie Dessalines d'Orbigny was a French naturalist who made major contributions in many areas, including zoology, palaeontology, geology, archaeology and anthropology.
Hyaenodon ("hyena-tooth") is an extinct genus of carnivorous placental mammals from extinct tribe Hyaenodontini within extinct subfamily Hyaenodontinae, that lived in Eurasia and North America from the middle Eocene, throughout the Oligocene, to the early Miocene.
Diatomys is an extinct rodent genus known from Miocene deposits in China, Japan, Pakistan, and Thailand. The fossil range is from the late Early Miocene to the Middle Miocene.
Atacisaurus is an extinct dubious genus of gavialoid crocodylian. Fossils have been found in the Grès de Carcassonne Member of the Sables du Castrais Formation in Laure-Minervois, France that date back to the Middle Eocene.
Iberosuchus is a genus of extinct sebecosuchian mesoeucrocodylian found in Western Europe from the Eocene. Remains from Portugal was described in 1975 by Antunes as a sebecosuchian crocodilian. This genus has one species: I. macrodon. Iberosuchus was a carnivore, unlike the crocodilians today, they are not aquatic and are instead terrestrial.
Quercygale is an extinct genus of placental mammals from extinct family Quercygalidae within clade Carnivoraformes, that lived in Europe during the early to late Eocene. Phylogenetic analysis of the basicranial morphology of carnivoramorphans suggests Quercygale is the most advanced member of clade Carnivoraformes as a sister taxon to crown group Carnivora, predating the split between Feliformia and Caniformia, although another recent study has proposed genus Quercygale should be placed as a stem group within Feliformia.
Tillodontia is an extinct suborder of eutherian mammals known from the Early Paleocene to Late Eocene of China, the Late Paleocene to Middle Eocene of North America where they display their maximum species diversity, the Middle Eocene of Pakistan, and the Early Eocene of Europe. Leaving no descendants, they are most closely related to the pantodonts, another extinct group. The tillodonts were medium- to large-sized animals that probably fed on roots and tubers in temperate to subtropical habitats.
Plithocyon is an extinct genus of hemicyonine bear of the Miocene epoch, endemic to North America and Europe. It lived from ~15.97—11.61 Ma, existing for approximately 4 million years.
Dollosuchus is an extinct monospecific genus of tomistomine crocodilian originally named as a species of Gavialis. It is a basal form possibly related to Kentisuchus, according to several phylogenetic analyses that have been conducted in recent years, and is the oldest known tomistomine to date. Fossils have been found from Belgium and the United Kingdom. It had large supratemporal fenestrae in relation to its orbits, similar to Kentisuchus and Thecachampsa.
Ferganosuchus is an extinct monospecific genus of gavialid crocodilian. The genus is thought to be a tomistomine, although it has been suggested that Ferganosuchus may be a more basal gavialoid. Fossils have been found in the region of Kazakhstan and Kyrgyzstan that date back the middle Eocene. The genus is well known from fairly complete specimens, unlike most other Asian tomistomines, whose remains tend to be more fragmentary.
Robert Julien Hoffstetter was a French taxonomist and herpetologist who was influential in categorizing reptiles. He described the snake families Bolyeriidae and Madtsoiidae.
Kentisuchus is an extinct genus of gavialoid crocodylian, traditionally regarded as a member of the subfamily Tomistominae. Fossils have been found from England and France that date back to the early Eocene. The genus has also been recorded from Ukraine, but it unclear whether specimens from Ukraine are referable to Kentisuchus.
Bruno R.C. Granier is Professor of Geology at the University of Brest (France), a post he held in 2004. He is the author of over 90 scientific papers.
Phosphatosaurus is an extinct genus of dyrosaurid crocodylomorph. It existed during the early Eocene, with fossils having been found from North Africa in Tunisia and Mali. Named in 1955, Phosphatosaurus is a monotypic genus; the type species is P. gavialoides. A specimen has been discovered from Niger, but it cannot be classified at the species level.
The Lignites de Soissonais is a geologic formation in the Var, Marne departments of France. It preserves fossils dating back to the Ypresian stage of the Eocene period.
The Quercy Phosphorites Formation is a geologic formation and lagerstätte in Occitanie, southern France. It preserves fossils dated to the Paleogene period, or MP16 to MP28 zones of the European land mammal age classification, ranging from approximately 38 to 25 Ma.
The Silveirinha Formation is an Early Eocene geologic formation of the Mondego Basin in the Região Centro of central-western Portugal. The sandstones, siltstones and conglomerates were deposited in an alluvial environment.
La Grive-Saint-Alban is a geomorphological karstic site located on the territory of the French commune of Saint-Alban-de-Roche, in the Isère department. This area, long exploited for its red clay, is known since the 19th century for the richness of its fossil deposits, distributed from the Bathonian stage to the Miocene.
The Sables du Castrais Formation, also known as the Molasses du Castrais, is a geologic formation of Eocene age, outcropping in the Montagne-Noire region of France.
Robiatherium is an extinct genus of Palaeogene artiodactyls containing one species R. cournovense. The genus name derives from the locality of Robiac in France where some of its fossil were described plus the Greek θήρ/therium meaning "beast" or "wild animal." It was known only from the middle Eocene and, like other anoplotheriids, was endemic to western Europe. The genus was erected by Jean Sudre in 1988 for a species originally attributed to the xiphodont genus Paraxiphodon in 1978. Robiatherium had dentitions typical of the subfamily Anoplotheriinae, differing from other genera by specific differences in the molars. It is one of the earliest-appearing anoplotheriine species in the fossil record as well as the earliest to have appeared in central Europe.
