The dental-wear proxies available to paleoecologists provide a mosaic of dietary evidence reflecting diet over long (mesowear) and more abbreviated (microwear) periods of time that, together, provide a richer understanding of feeding ecology and its relationship to environment, seasonal change, and other ecological disturbances. Height, 48 to 58 inches length, eight to 10 feet Weight: 1,760 pounds Size relative to a 6-ft man: IUCN Red List Status: Critically endangered LC NT VU EN CR EW EX Least Concern Extinct Current. They can break off or wear down, but will grow back over time since they are a mass of keratin (the same. Some, but not all, mass-death assemblages produce microwear data with excessive scratches and/or pits compared with expectations based on mesowear results, suggesting that dental microwear was altered shortly before death in some but not all of the fossil assemblages. Modern rhinoceroses are large animals, ranging from 2.5 metres (8 feet) long and 1. Rhino horns are primarily used for protection. ![]() Mesowear suggests that the fossil rhinos had low-abrasion diets, suggesting that they fed from clean, possibly tall vegetation. ![]() In contrast, a relationship between mesowear and microwear was not observed among the fossil rhinocerotid assemblages. Mesowear and microwear in the modern rhinocerotid collections are statistically correlated, with strong relationships between average mesowear scores and labially distributed dental microwear. In extant rhinos, both mesowear and microwear are associated with diet and height of the feeding environment. Modern rhinoceroses are large animals, ranging from 2.5 metres (8 feet) long and 1.5 metres (5 feet) high at the shoulder in the Sumatran rhinoceros to about 4 metres (13 feet) long and nearly 2 metres (7 feet) high in the white rhinoceros. We compared congruence between microwear and mesowear of North American, fossil rhinocerotid mass-death assemblages and collections of hunted modern rhinocerotids to test the hypothesis that fossil assemblages yield more incongruous microwear and mesowear data as a result of near-death ecological disturbances. Also known as the square-lipped rhinoceros, white rhinos have a square upper lip with almost no hair. Mesowear, another dental-wear proxy based on the morphology of worn cusps, requires macroscopic amounts of dental wear and reflects diet for a longer interval and may be less prone to bias from near-death ecological stress. White rhinos are the second-largest land mammal and their name comes from the Afrikaan’s, a West Germanic language, word weit which means wide and refers to the animal’s mouth. ![]() In these instances, dental microwear, which reflects feeding ecology in a narrow window of time, may provide a biased view of diet. Although we do not know the cause of death of most fossil animals, mortality is often associated with ecological stress due to seasonality and other stochastic events (droughts, storms, volcanism) that may have caused shifts in feeding ecology preceding death.
