Beschreibungen/Notizen

• The developmental or usage patterns experienced in the dentition by certain mammals during their growth or later in life often are preserved in their fossilized remains and have extensively been used in reconstructing life-history or the habitat in which the animals lived. One such, though lesser emphasized, feature is the enamel hypoplasia (EH), which is a failure for the enamel to form properly leaving distinct linear or curved marking(s) on the teeth. EH is caused by environmental or physiological stresses in an animal's life at that particular time when the growth was taking place. Hence, the EH analysis in a faunal accumulation has been used for providing a unique perspective into environmental conditions present during the growing years of an extinct animal's life. The present study on EH of Siwalik Rhinocerotids has proved to be an important tool for not only understanding their past life-history but also in reconstructing local palaeoenvironment and regional palaeoclimate of the region.
