They found numerous fossils, but at first no hominids. Then, in November 1973, near the end of the first field season, Johanson tapped a fossil fragment he thought was a hippopotamus rib. He found that it was actually a fossil of a proximal tibia, the upper end of a shinbone. From its small size, he thought it was a monkey, and decided to ...
In medieval China, the fossil bones of ancient mammals including Homo erectus were often mistaken for "dragon bones" and used as medicine and aphrodisiacs. In addition, some of these fossil bones are collected as "art" by scholars, who left scripts on various artifacts, indicating the time they were added to a collection.
Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. [57] Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time.
Jefferson presented fossil bones of a ground sloth found in a cave in western Virginia and named the genus . The species was ultimately named Megalonyx jeffersonii in his honor. [ 4 ] [ 5 ] [ 6 ] Jefferson corresponded with Cuvier, including sending him a shipment of highly desirable bones of the American mastodon and the woolly mammoth .

Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural ...
The fossil record is very uneven and, with few exceptions, is heavily slanted toward organisms with hard parts, leaving most groups of soft-bodied organisms with little to no fossil record. [39] The groups considered to have a good fossil record, including a number of transitional fossils between traditional groups, are the vertebrates, the ...
Most pathologies preserved in theropod fossils are the remains of injuries, but infections and congenital deformities have also been documented. [1] Pathologies are less frequently documented in small theropods, although this may simply be because the larger bones of correspondingly larger animals would be more likely to fossilize in the first ...
