Massive dinosaur discovered in Antarctica sheds light on life, distribution of sauropodomorphs
Date:12/10/2007

f this debate by establishing two things. First, it shows that sauropodomorphs were widely distributed in the Early Jurassicnot only in China, South Africa, South America and North America, but also in Antarctica.

This was probably due to the fact that major connections between the continents still existed at that time, and because climates were more equitable across latitudes than they are today, Smith said.

Second, the discovery of Glacialisaurus hammeri shows that primitive sauropodomorphs probably coexisted with true sauropods for an extended period of time. The recent discovery of a possible sauropod at roughly the same location in Antarctica lends additional evidence to the theory that the earliest sauropods coexisted with their basal sauropodomorph cousins, including Glacialisaurus hammeri, during the Late Triassic and Early Jurassic, Smith and Pol conclude in their research findings.
