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)[2] and Uruguay (Santa Lucía Basin).[3] The Brazilian species, alongside Eoborus charruanus from Uruguay, are the oldest fossil record of the family.[2]
The small size and large umbilicus of Eoborus are its most remarkable characteristics; it is considered primitive in the family Strophocheilidae.[2][1]
Species
Species within the genus Eoborus include:
- Eoborus berroi Klappenbach & Olazarri, 1986[4] - from Uruguay
- Eoborus charruanus (Frenguelli, 1930) - from Uruguay and Argentina - type species of genus
- Eoborus fusiforme Salvador & Simone, 2013[5] - from Brazil
- Eoborus rotundus Salvador & Simone, 2012[2] - from Brazil
- Eoborus sanctijosephi (Maury, 1935)[6] - from Brazil
Some authors note that two other species, Strophocheilus chubutensis and Strophocheilus hauthali could also belong to Eoborus.[1][3]
