The Warrawoona Group is a geological unit in Western Australia containing putative fossils of cyanobacteria cells. Dated 3.465 Ga, these microstructures, found in Archean chert, are considered to be the oldest known geological record of life on Earth. [1] [2] [3]
McGraths Flat is an Australian research site containing fossils and other evidence of animals and plants that existed in Miocene Australia. Located in central New South Wales, specimens at the site are in an exceptional state of preservation, described in paleontology as a Konservat-Lagerstätten, deposited in unusual conditions that record microscopic details of soft tissues and delicate ...
The fossil bird fauna at Riversleigh includes an artamid Kurrartapu johnnguyeni, a fossil sittella, [12] and representatives of various other families of modern birds. [13] [14] [15] Some fossil insects and plants have also been discovered. [4] The fossil species identified at the sites are collectively known as the Riversleigh fauna. [16]
The genus was established by John W. Cosgriff in 1969 to incorporate the type, discovered in New South Wales, and the author's new fossil species, Blinasaurus henwoodi, describing type material found in Blina Shale in the Kimberley region of northwest Australia.
A rare fossil of an adolescent Tyrannosaurus rex has been excavated in North Dakota's badlands - a find noteworthy for the scientific insight it may offer into the life history of this famous ...
Lacerda et al. (2024) describe new fossil material of spinosaurids (including a cervical vertebra of Sigilmassasaurus) and partial ischium of an indeterminate carcharodontosaurid from the Kem Kem Group . [167] Yun (2024) identifies convergent similarities in craniodental anatomy between spinosaurs and phytosaurs. [168]
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
[3] [4] A local apiarist later found this slab and, believing it to contain fossils, contacted the Australian Museum about it. In 1993 paleontologist Alex Ritchie led a dig at the site of the initial fossil discovery. That dig led to the removal of 70 tonnes of rock slab and revealed over 3,000 fish fossils from the Devonian period.
