Morphological comparisons of mammals between fossils from Myanmar and recent materials from India

Report: YUICHIRO NISHIOKA

Date: 2012/5/27 - 2012/6/17

  I visited to the Bombay Natural History Society in Mumbai, and observed extant specimens of mammals from India for comparing with mammalian fossils from the Plio-Pleistocene Irrawaddy sediments in Myanmar. I collected morphological data such as measurements and dental molds of the following specimens; Cercopithecidae (Semnopithecus), Bovidae (Antilope, Capricornis, Boselaphus, Tetracerus, Gazella), Tragulidae (Moschiola), Muridae (Maxomys, Madromys, Golunda, Rattus, Millardia), Spalacidae (Cannomys), and Hystricidae (Hystrix, Atherurus). In Myanmar, I excavated fossils of small mammals in Gwebin area and collected 4specimens of Semnopithecus and 93 specimens of rodents by a screen-wash method. Moreover, I drew a geological columnar section of the Irrawaddy sediments yielding the fossils of monkeys and rodents. After the excavating research, I arranged the specimens discovered until now and got the morphological data fromthese specimens for my doctoral thesis. I also reconsidered the specimens of rodents and bovids, comparing with the extant materials I observed in the Bombay Natural History Society.
