Abstract
Abstract. The first fossil record of Duboisia (Boselaphini, Bovidae) from
Thailand confirms that this genus is no longer endemic to Java, Indonesia.
The new fossil material is a calvarium with horn cores (older than the Middle
Pleistocene) collected from a sandpit at Tha Chang, Nakhon Ratchasima
Province, north-eastern Thailand. The present specimen is provisionally
allocated to a species of Duboisia aff. D. santeng, which
has weaker precornual ridges and anterior keels on the horn cores than
D. santeng from Early and Middle Pleistocene deposits of Java, but
these species share basic characteristics of horn cores as follows: the lower
half inclined backwards; the upper half curved upwards; cross section rounded
triangular, antero-posteriorly compressed, and with medial and lateral keels.
Morphological similarities between D. aff. santeng and D. santeng support a strong faunal interchange between continental South East Asia
and Java before the Middle Pleistocene, and suggest that the genus
Duboisia diverged from the other genera of Boselaphini in the
“Siva-Malayan” region.
期刊介绍：
Fossil Record (FR) is the palaeontological journal of the Museum für Naturkunde Berlin. This journal was founded in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe and appears with two issues each year. Fossil Record publishes original papers in all areas of palaeontology including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. All taxonomic groups are treated, including invertebrates, microfossils, plants, and vertebrates.
