Titanoboa, meaning "titanic boa", is an extinct genus of snake that lived approximately 60 to 58 million years ago, during the Paleocene epoch, (approximately 60-58 million years ago) a 10-million-year period immediately following the Cretaceous–Tertiary extinction event that wiped out the majority of terrestrial life, including the dinosaurs. After the mass extinction event, Titanoboa was, for the majority of the Paleocene epoch, the largest non-marine vertebrate. It is the largest snake ever discovered at an estimated 43 feet long, and to date, paleontologists have identified about 180 different bones, mainly vertebrae and costae (rib bones) belonging to 28 individual specimens from a cache of fossils excavated from El Cerrejon coal mine in northern Colombia. The prepped fossils were later revealed in early 2007 at the University of Florida's Florida Museum of Natural History in Gainesville, Florida. However, this is not the first occurence of large snake fossils that have been discovered in South America before. An example would be Madtsoia bai, a huge constrictor known from fossils discovered in Argentina in the mid 1930s. This particular species was believed to be up to 12 meters long, huge by modern snake standards but still 20% smaller than Titanoboa. (Read more...)

Paul Sereno

Paul Sereno is an American paleontologist who is the discoverer of several new dinosaur species on several continents. He has conducted excavations at sites as varied as Inner Mongolia, Argentina, Morocco and Niger. He is a professor at the University of Chicago and a National Geographic "explorer-in-residence." Sereno's most widely publicized discovery is that of a nearly complete specimen of Sarcosuchus imperator (popularly known as SuperCroc) at Gadoufaoua in the Tenere desert of Niger. Other major discoveries include Eoraptor - the oldest known dinosaur fossil, Jobaria, the first good skull of Carcharodontosaurus iguidensis, Afrovenator, Suchomimus and the African pterosaur.

"Cryolophosaurus is also of significance because it represents the oldest known tetanuran from any continent — it is the only one from the Early Jurassic."

Crurotarsi

The Crurotarsi ("cross-ankles") are a group of archosaurs, whose name was erected as a node-based clade by Paul Sereno in 1991 to supplant the old term, Pseudosuchia. Crurotarsi are by definition the sister group of the Avemetatarsalia (all forms closer to birds than crocodiles). Crurotarsi is one of the two primary daughter clades of the Archosauria. The skull is often massively built, especially in contrast to ornithodires; the snout narrow and sometimes tending to be elongate, the neck is short and strong, and the limb posture ranging from typically reptilian sprawling to dinosaur or mammal-like erect (although this is achieved in a different way to dinosaurs and mammals). The body is often protected by two or more rows of armored plates. Many crurotarsans reached large size: approximately around three meters or more in length.

Clockwise from top-left: Longosuchus meani (an aetosaur), Angistorhinus grandis, (a phytosaur), Saurosuchus galilei (a rauisuchian), Pedeticosaurus leviseuri (a sphenosuchian), Chenanisuchus lateroculi (a eusuchian), and Dakosaurus maximus (a thalattosuchian).
