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 ...
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.
Approximately 6,000 years ago, prehistoric humans living in southern China were among the first people to eat cooked food. Now, fossils unearthed in the Zuojiang River Basin in the Guangxi region ...
Fossils of at least some of these animals (Scansoriopteryx and possibly Juravenator) also preserve feathers elsewhere on the body. Though once thought to be a feature exclusive to coelurosaurs, feathers or feather-like structures are also known in some ornithischian dinosaurs (like Tianyulong and Kulindadromeus ), and in pterosaurs .
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.
Stromatolites are some of the oldest fossils in the park at over 1 billion years old. South Kaibab Trail: This is one of the most popular trails and if you look carefully you will notice fossils ...
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 ...
Fossils have been found in marine strata. The nares are retracted and the orbits are raised like in other aquatic mammals. Levels of stable isotopes in their tooth enamel suggest an aquatic diet and environment (carbon and oxygen) and fresh or brackish water (strontium).
