T. haysii was named previously by Joseph Leidy in 1860 [31] before a host of new fossils were described by Cope. [2] [3] Later in 1945, George Gaylord Simpson referred all of the Port Kennedy fossils to a new species he dubbed T. copeii, [32] a junior synonym of T. haysii due to lack of sufficient distinguishing traits.

A microscope image of subdermal muscle from the ancient skin shows remnants of mammoth nuclei. The new study revealed that fossils of ancient chromosomes survive in this skin sample.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
An intriguing arthropod ancestor. The 3D scans revealed two nearly complete specimens of Arthropleura that lived 300 million years ago. Both fossilized animals still had most of their legs, and ...
2009 — Fossils of Titanoboa, a giant snake, are unearthed in the coal mines of Cerrejón in La Guajira, Colombia, suggesting paleocene equatorial temperatures were higher than today. [16] 2016 — Tail fossils of a baby species of Coelurosaur, fully preserved in amber including soft tissue, are found in Myanmar by Lida Xing [17]
There have been some discoveries of unusually well-preserved fossil dinosaur specimens which bear remnants of tissues and bodily structures.Organic tissue was previously thought to decay too quickly to enter the fossil record, unlike more mineralised bones and teeth, however, research now suggests the potential for the long-term preservation of original soft tissues over geological time, [1 ...
The Gondwanax fossil material was discovered in 2014 by physician and paleontology enthusiast Pedro L. P. Aurelio at the "Linha Várzea 2" ("Becker") site, belonging to the Pinheiros-Chiniquá Sequence of the Santa Maria Supersequence (Formation) in Paraíso do Sul municipality of Rio Grande do Sul, Brazil.
The fact that so many fossils of Ptychodus have been found in different regions of the world provides evidence of a distribution of species during the Albian-Turonian time. [6] The generic name Ptychodus comes from the Greek words ptychos (fold/layer) and odon (tooth), so "fold teeth" describing the shape of their crushing and grinding teeth. [11]
