Eoborus is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Strophocheilidae. Eoborus is the oldest fossil record of Strophocheilidae, dating from the Middle Paleocene of Brazil ( Itaboraí Basin) [1] and Uruguay (Santa Lucía Basin). [4] The Brazilian species, alongside Eoborus charruanus from Uruguay, are the oldest fossil record of the family. [1]
The small size and large umbilicus of Eoborus are its most remarkable characteristics; it is considered primitive in the family Strophocheilidae. [1] [3]
Species within the genus Eoborus include:
Some authors note that two other species, Strophocheilus chubutensis and Strophocheilus hauthali could also belong to Eoborus. [3] [4]
