| | Tragoportax (mammalia, Bovidae) From The Dhok Pathan Formation Of The Middle Siwaliks, Northern Pakistan | | | Author Name:Ammara Nawaz ,Hasnain Nangyal ,Nighat Ziaudin ,Ali Raza and Upvan Bhushan |  | | Show Author Profile | | Abstract: Dhok pathan formation of Chakwal district, Punjab Pakistan is famous for the
formation of new bovid remains of Tragoportax punjabicus. The recovered material
consists of upper and lower dentition with isolated molars too. All the fossil remains has
been described in detail to establish the T axonomic Position of the specimen up to
species level. Material is described fully in the thesis and measurements were also taken
then compar ed with the pr eviously described fossils of Tragoportax punjabicusto get a
satisfactory conclusion. Abundance of boselaphines in Dhok Pathan Formation indicate
that Siwaliks was inhabited by great variety of boselaphines and many new forms
appeared in Miocene and diversified in the later epochs including the studied specie
Tragoportax punjabicus .The collected fossils of boselaphine fauna greatly helps in the
reconstruction of paleohabitat, paleoenvironment and other conditions of the ancient
and extinct animals specially Tragoportax punjabicus in Dhok Pathan Formation of
Middle Siwaliks. The collected fossils show similarity with the established diagnostic
featur es of the genus Tragoportax and the species Tragoportax punjabicus was
established due to most sibling similarities including description of theupper molars
which arequadrate, moderately hypsodont, outer folds and ribs rather strong, median
rib in posterior lobe is weaker than in anterior lobe, entostyles present in all the molars. |
