Range of P. nivalis
Range of P. nivalis

Pennatomys nivalis is an extinct oryzomyine rodent from the islands of Sint Eustatius, Saint Kitts, and Nevis in the Lesser Antilles (range pictured). It is known from skeletal remains found in Amerindian archeological sites on all three islands, with dates ranging from 790–520 BCE to 900–1200 CE. No live specimens are known, but there are several historical records of rodents from Saint Kitts and Nevis that could conceivably refer to Pennatomys. The animal apparently belongs to a group within the tribe Oryzomyini that includes many other island-dwelling species. Pennatomys nivalis was a medium-sized species without many distinctive adaptations. The nasal bones were short and blunt-ended. The zygomatic plate, a bony plate at the side of the skull, was broad. The bony palate was long and flat. The root of the lower incisor was housed in a bony protuberance, the capsular process. The molars were low-crowned and possessed accessory crests such as mesolophs. The upper molars all had three roots. (Full article...)

NASA space-flown Apollo medallion for the Apollo–Soyuz mission.


Apollo–Soyuz was the first crewed international space mission, carried out jointly by the United States and the Soviet Union in 1975. A United States Apollo capsule and a Soviet Union Soyuz capsule launched into orbit on July 15, and millions of people around the world watched on television two days later as the spacecraft docked and the two crews shook hands through the hatch. The project was a symbol of détente between the two superpowers during the Cold War, and it is generally considered to mark the end of the Space Race, which had begun in 1957 with the Soviet Union's launch of Sputnik 1.
