A living fossil is an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be.
Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
Fossil remains of Hyracotherium show it to have differed from the modern horse in three important respects: it was a small animal (the size of a fox), lightly built and adapted for running; the limbs were short and slender, and the feet elongated so that the digits were almost vertical, with four digits in the forelimbs and three digits in the ...
When people think fossils, dinosaurs typically come to mind – but that’s only one part of the picture. ... These animals lived in a very different environment than what exists today, said Adam ...
This gives an insight on how humans began domesticating animals. In zooarchaeology, studies will show the animal and human husbandry, as well as the process of cultures adding animals into their diets. [12] Studying animals in archaeology requires the help from different fields such as zoology, anthropology, paleontology, osteology, and anatomy ...
Prehistoric flying reptiles lived on a diet of small fish and squid, the latest scientific research has shown. Researcher Dr Roy Smith said stomach contents discovered in fossils were the "smoking ...
[57] [63] Trace fossils are particularly significant because they represent a data source that is not limited to animals with easily fossilised hard parts, and they reflect organisms' behaviours. Also many traces date from significantly earlier than the body fossils of animals that are thought to have been capable of making them. [64]
A derived, reworked or remanié fossil is a fossil found in rock that accumulated significantly later than when the fossilized animal or plant died. [98] Reworked fossils are created by erosion exhuming (freeing) fossils from the rock formation in which they were originally deposited and their redeposition in a younger sedimentary deposit.
