A new genus of Ungulate mammal has been named after Lady Gaga. Gagadon minimonstrum (translates to: Gaga tooth small monster) is described in the May edition of Journal of Vertebrate Paleontology. The new mammal represents a previously unknown evolutionary branch of a now extinct family. Gagadon lived during the Early Eocene Climatic Optimum. This was a period of relative warmth around 55 million years ago and the mammal faunas of this time can provide a valuable insight into how evolution responds to a warmer climate.
Samples of artiodactyl fossil populations from the early Eocene of North America provide one of the best data sets for studying long-term evolutionary patterns and relationships of groups above the species level because of the excellent stratigraphic control, geographic extent, morphological variability, and abundance of specimens
