Coalsack Bluff exposes a paleontologically important, fossiliferous sequence of sedimentary rocks containing the Permian–Triassic boundary. This bluff is a fossil location that has yielded well preserved
Permian and
Triassic and plant,
invertebrate, and
vertebrate fossils and
paleosols that reveal the paleoclimatic and paleontologic changes associated with the
Permian–Triassic extinction event. It is the location where abundant fossils of Early Triassic
tetrapods were first discovered in Antarctica. The vertebrate fossils found at this location are important in understanding the
biostratigraphy and vertebrate paleontology of Permian and Triassic strata in Antarctica. == See also ==
