Early Carboniferous tetrapods in Australia

Article Abstract:

Tetrapod fauna discovered in the Drummond basin, Australia, are of Early Carboniferous age with some of them originating from Europe and North America, indicating their worldwide distribution through equatorial regions. The fauna reveals at least three types of tetrapods along with freshwater fishes. Two of these are distantly linked to living amphibians, whereas the third shows early links to amniotes. The early age, taxonomic diversity and geographical remoteness of these tetrapods advances data on early tetrapod history.

Fishy fragments tip the scales

Article Abstract:

The 510-Myr-old skeletal fragments discovered from Cambrian rocks sheds light on the diversity of exoskeletal structures. These skeletal fragments are believed to belong to one of the earliest vertebrates, indicating that they consist of relatively large plates. This hypothesis contradicts the theory that the primitive vertebrate exoskeleton is made up of minute, independent scales. However, the claim that these fragments are from primitive vertebrates is controversial.
