Pseudarmadillo tuberculatus

Pseudarmadillo tuberculatus is an extinct species of isopod in the family Delatorreidae known from a series of possibly Miocene fossils found on Hispaniola. At the time of description P. tuberculatus was one of two Pseudarmadillo species known from the fossil record and one of only two from Hispaniola.

P. tuberculatus is known from four isopods, both female and male, all of which are inclusions in three different transparent chunks of Dominican amber. Two of the paratypes are fossils in the same amber specimen while the other two individuals are both in separate amber specimens. The amber specimens which entomb the holotype and paratypes, are currently preserved in the Division of Invertebrate Zoology collections at the Staatliches Museum für Naturkunde Stuttgart in Stuttgart, Germany. The type specimens were collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic. The amber was produced by resin from the extinct tree Hymenaea protera, which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The amber dates from at least the Burdigalian stage of the Miocene, based on studying the associated fossil foraminifera and may be as old as the Middle Eocene, based on the associated fossil coccoliths. This age range is due to the host rock being secondary deposits for the amber, and the Miocene the age range is only the youngest that it might be.
