Punjab University Department of Zoology's PhD student Ghayyour Abbas has made a marvelous discovery of a rare 3.3 million-year-old elephant tusk fossil from the Village Tatrot in Sohawa Tehsil of District Jhelum. The tusk fossil perhaps belongs to the extinct Anancus genus of elephants, who roamed in the primitive forest habitat of Jhelum some 3.5 million years ago and measures approximately 6 feet. Siwalik Mountain geological formation range in Jhelum,Chakwal and Miawali districts is famous for rare elephant fossils as the geological range is regarded as the paradise of elephant fossils all over the world.
In an alarming but significant ground breaking environment research, Punjab University PhD scholar Muhammad Sohail has found that freshwater mussels (Anodonta anatine) being sensitive to aquatic environmental contamination are excellent indicators of ecosystem health and stability. According to a press release issued here on Tuesday, freshwater mussels, close relatives of pearls producing oyster mollusks are immobile and imbedded in the river streambed and filter water to obtain oxygen and food; therefore, they are sensitive to industrial, agricultural and other anthropogenic contaminations polluting even River Indus.
The researcher has found bio-accumulation of Lead, Copper and Chromium heavy metals in the gills, mantle and foot of freshwater mussels collected from River Indus and Chashma Barrage bed. PU Vice Chancellor, Prof. Dr. Zaffar Mueen Nasir has congratulated Muhammad Sohail on successful completion of his PhD degree on the basis of such excellent PhD evaluation reports.
