About: Agathaeromys

An Entity of Type: Rodent102329401, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Agathaeromys is an extinct genus of oryzomyine rodents from the Pleistocene of Bonaire, Netherlands Antilles. Two species are known, which differ in size and some details of tooth morphology. The larger A. donovani, the type species, is known from hundreds of teeth that are probably 900,000 to 540,000 years old, found in four localities. A. praeuniversitatis, the smaller species, is known from 35 teeth found in a single fossil site, which is probably 540,000 to 230,000 years old.

  • Agathaeromys is an extinct genus of oryzomyine rodents from the Pleistocene of Bonaire, Netherlands Antilles. Two species are known, which differ in size and some details of tooth morphology. The larger A. donovani, the type species, is known from hundreds of teeth that are probably 900,000 to 540,000 years old, found in four localities. A. praeuniversitatis, the smaller species, is known from 35 teeth found in a single fossil site, which is probably 540,000 to 230,000 years old. Although material of Agathaeromys was first described in 1959, the genus was not formally named and diagnosed until 2010. It probably belongs to "clade D" within the oryzomyine group, together with many other island-dwelling species. The molars of both species possess several accessory crests in addition to the main cusps. In addition to some differences in features of the chewing surface of the molars, A. donovani has more roots on its lower molars than does A. praeuniversitatis. (en)
  • Agathaeromys Zijlstra et al., 2010 è un genere estinto di roditori del Pleistocene, rinvenuti nell'isola di Bonaire, nei Paesi Bassi caraibici. Nel genere sono riconosciute due specie, che si differenziano soprattutto per le dimensioni e la morfologia dentale. La specie più grande, A. donovani, individuata in diverse località e risalente probabilmente da 540.000 a 900.000 anni fa, è dotata di centinaia di denti. La A. praeuni -versitatis, la specie più piccola, possiede 35 denti e venne ritrovata in un solo sito di fossili, probabilmente risalente da 230.000 a 540.000 anni. I primi studi sull'Agathaeromys risalgono al 1959, ma la descrizione attuale risale solo al 2010 e appartiene al del gruppo . I molari presentano in entrambe le specie delle creste accessorie in aggiunta alle cuspidi. Oltre alle differenze nella masticazione, A. donovani possiede più radici di A. praeuniversitatis. (it)
