Stone tools and butchered animal remains dating to 2.6 million years ago have been found together in Ethiopia. This finding provides both the clearest evidence of meat eating by early human ancestors and the association of earliest stone tools with the butchering of animals for meat and marrow. [8]
Trace fossils provide us with indirect evidence of life in the past, such as the footprints, tracks, burrows, borings, and feces left behind by animals, rather than the preserved remains of the body of the actual animal itself. Unlike most other fossils, which are produced only after the death of the organism concerned, trace fossils provide us ...
While most modern mammals begin showing up in fossil records dating back 60 million years, monotremes are thought to have evolved around 130 million years ago. ... Platypuses eat small fish, worms ...
Zooarchaeology which is the study of animal remains from archaeological sites is able to provide insight into the diet of both humans and animals, resource use, the economy, climate, technological adaptations, human demography, urbanisation and a wide variety of information about how humans operated within their environment.
Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived. The predator, which was larger than a person, likely used ...
While some fossil gastroliths are rounded and polished, many stones in living birds are not polished at all. Gastroliths associated with dinosaur fossils can weigh several kilograms. Certain crayfish store gastroliths in their stomachs. Crayfish living in freshwater store these gastroliths as the presence of calcium is limited in freshwater.
A fossil preparator handles fossils found in Petrified Forest National Park at the museum's demonstration lab. Visitors are not allowed to take fossils from the park.
Ten species of fossil dinosaurs from five taxonomic groups reveal indices even higher than in mammals, when body size is accounted for, indicating that they were highly active, aerobic animals. Thus high blood flow rate, high blood pressure, a four-chambered heart and sustained aerobic metabolism are all consistent with endothermy .
