We describe here a suid molar originating from the Late Miocene Dhok Pathan type locality (Chakwal, Punjab, Pakistan) of Dhok Pathan Formation, Middle Siwaliks, Northern Pakistan. The molar belongs to the large sized Pliocene suid Tetraconodon. The specimen, which is attributed to a tetraconodon, reliably matches with T. magnus, a rare taxon previously found in the Pliocene of the Siwaliks. The presence of this species in the Late Miocene of the Dhok Pathan type locality represents the oldest record in the Siwaliks.
NEW COLLECTION OF CONOHYUSSINDIENSIS, A MIDDLE MIOCENE SUID, FROM CHAKWAL, PAKISTAN
New fossils of Conohyussindiensis have been collected from Middle Miocene localities of Lawa, Kallar Kahar and Dhok Bun Ameer Khatoon in district Chakwal. Conohyussindiensis is very common suid in the Chinji type area of Pakistan. Its biostratigraphic range varies between Kamlial type areas to the base of Nagri Formation. The probable time range of C. sindiensis is from 15 to 11 million years. The sample comprises isolated molars. The morphometric description of these specimens will add new information regarding molar morphology as well as the biogeographic distribution of Conohyussindiensis.
Description of Gazella sp. from the Middle Miocene Siwaliks of Punjab, Pakistan
Punjab University Journal of Zoology, 2018
is recorded from 13.2-12.0 Ma (Gentry et al., 2014). According to Gentry (1999) and Kostopoulos (2009), the species level variety of this genus declined in the Asian region during the Pliocene due to cooler and unpredictable climatic conditions of this epoch but the genus maintained its survival in Africa and Middle East region during this interval. Dhok Bun Ameer Khatoon is a fossil area that comprises five Siwalik formations i.e. Kamlial, Chinji, Nagri, Dhok Pathan and Soan. The Chinji Formation fossil site is located in Chakwal District (32 o 47' 26.4" N 72° 55' 35.7" E) Punjab, Pakistan. The Chinji section lithology is identified by red-brown mudstone and common grey sandstone interbeds. According to Barry et al. (2002) and Cheema (2003), the fluvial deposits in these localities are mainly filled by sedimentary rocks in an unweathered condition.
New Fossils of Suidae (Mammalia, Artiodactyla) from the Hasnot Late Miocene, Northern Pakistan
A variety of suids from the Dhok Pathan Formation of the Middle Siwaliks are identified, described and discussed in this paper. The new remains were recovered from the Late Miocene continental deposits, located in the vicinity of the Hasnot village, Jhelum district, Punjab province, Pakistan. A three suid species namely Propotamochoerus hysudricus, cf. Hippohyus sivalensis and Hippopotamodon sivalense have been identified. A documentation of the new remains is the objective of this paper.
Cervid remains from the middle Siwaliks of Hasnot (Late Miocene), Pakistan
Journal of the Geological Society of India, 2014
The late Miocene-early Pliocene fossil deposits of Hasnot in northern Pakistan have yielded a very rich vertebrate fauna. In this paper we describe the remains of Cervidae from six of these localities. By dental remains, at least four species of cervids are documented. These remains significantly widen the time distribution of the cervids and draw back the first appearance of cervids in the Dhok Pathan Formation of the Siwaliks. The data indicate a diverse set of coexisting ungulates in the area, subsisting within a mosaic of habitats.
Paleontological Research, 2016
New fossil material from the latest early Miocene Manchar Formation in the Ranikot area (Sindh, Pakistan) provides information about the poorly known listriodontine suid Listriodon guptai Pilgrim, 1926. Recognition of this taxon, initially described on the basis of a fragmentary upper molar, allows biochronologic correlations for the base of the Manchar Formation with penecontemporaneous formations of Pakistan where this taxon also occurs (Sulaiman Range and Potwar Plateau). Listriodon guptai may be closely related to the bunolophodont species Listriodon affinis of doubtful stratigraphic provenance and age in the Bugti Hills, as well as to the fully lophodont Listriodon pentapotamiae which occurs throughout the Chinji Formation in the Potwar Plateau. The early occurrence of these taxa pleads for an early diversification of the listriodonts in the Indo-Pakistan Subcontinent during the late early Miocene.
Propotamochoerus hysudricus remains from late Miocene deposits of Hasnot, Pakistan
2016
New fossil remains of the Suid species, Propotamochoerus hysudricus are described in this paper on the basis of their morphometric characters. This is perhaps the only known species of the genus Propotamochoerus in the Siwaliks. The specimens are collected from the outcrops of Hasnot type locality, Punjab, Pakistan. The present findings will strengthen the previous records of the species Propotamochoerus hysudricus from the Late Miocene Siwaliks of Pakistan. This species can act as a marker suid species of the Late Miocene Siwalik deposits.
