Palaeanodonta ("ancient toothless animals") is an extinct clade of stem-pangolins. They were insectivorous (myrmecophagous), possibly fossorial, and lived from the middle Paleocene to early Oligocene in North America, Europe and Asia.[3][5][6] While the taxonomic grouping of Palaeanodonta has been debated,[7] it is widely thought that they are a sister group to pangolins.[8][9][5][10]
