The scientific community has accepted the idea that birds evolved from a branch of the dinosaur tree. What evolutionary biologists haven't figure out, however, is how wrists evolved from straight to bent and hyperflexible.

The early stages of the process through which birds evolved from dinosaurs was slow and gradual, and there was no single “missing link” separating the two different types of creatures, according to research published in Thursday’s edition of the journal Current Biology.

Originally believed to have occurred around the same time that mammals evolved some 200 million years ago, researchers from the Field Museum of Natural History in Chicago now report that the transition to nocturnal behavior actually occurred more than 100 million years earlier.

Robert Thomas Bakker (born March 24, 1945) is an American Paleontologist known for his contribution to the “Dinosaur Renaissance” and his support of his mentor Ostrom’s theory that some dinosaurs were warm-blooded. He specializes in the ecological context and behavior of dinosaurs. Bakker was born in Bergen County, New Jersey. As a young boy, he developed an interest in dinosaurs following his first trip to the dinosaur exhibit at the American Museum of Natural History – he was...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...

Zooarchaeology
2013-09-30 13:29:48

Zooarchaeology is the study of animal remains including shells, bones, hides, scales, DNA, chitin, and hair. Shells and bones are most frequently studied because these do not decay at a fast rate, but most remains do not survive because they break or decompose. In eastern areas of North America, Zooarchaeology developed over three periods. The first, known as the Formative period, occurred in the 1860s and was not a specific area of study at that time. The second period, known as the...

Seitaad, derived from a Navajo legend of a san monster with the same name -- "Seit'aad," is a genus of prosauropod dinosaur from the Early Jurassic Period. The type species, S. ruessi, was described in 2010 based on fossils recovered from the Navajo Sandstone Formation in southern Utah. It is known from a nearly complete fossil that appears to have been entombed by the collapse of a sand dune about 185 million years ago. Based on the fossil, the dinosaur would have been 10 to 15 feet long...
