Dr. Robert T. Bakker, is said to be the most prominent and widely known expert in Paleontology. He was the scientist who hypothesized that dinosaurs as warmblooded . He also authored a book entitled the Dinosaur Heresies. During his out of town works, he discovered dinosaurs that live in an aquatic location and others which dwelt in trees.

One of his important accomplishments during his career was Epantarias. It was in 1990 that his team together with Bakker have dug neck and tail bones, jawbones, and teeth north of Denver, Colorado. He later observed that the bones they discovered came from an astonishing animal. He depicts the bones as part of the final member of Allosaur group, which was once inhabited North America, with its major bones like the skulls and legs resembles that of the Allosaur.

"The paleontology career of Dr. Robert T. Bakker has been full of exciting finds and controversial theories. While he may draw fire for some of his ideas, it is safe to say that Bakker's theories have led to the new image of dinosaurs-smart, active, caring, and highly interesting beasts!"

Robert T. Bakker (born March 24, 1945) is an American paleontologist who helped reshape modern theories about dinosaurs, particularly by adding support to the theory that some dinosaurs were endothermic (warm-blooded).

Along with his mentor John Ostrom, Bakker was responsible for initiating the ongoing "dinosaur renaissance" in paleontological studies, beginning with Bakker's article "Dinosaur Renaissance" in Scientific American, April 1975. His special field is the ecological context and behavior of dinosaurs.

Bakker has been a major proponent of the theory that dinosaurs were "warm-blooded", smart, fast, and adaptable. He published his first paper on dinosaur endothermy in 1968.

He revealed the first evidence of parental care at nesting sites for Allosaurus. Bakker was among the advisors for the film Jurassic Park and for the 1992 PBS series, The Dinosaurs.

He also observed evidence in support of Eldredge's and Gould's theory of punctuated equilibrium in dinosaur populations. Bakker currently serves as the Curator of Paleontology for the Houston Museum of Natural Science.

Theories:

In his 1986 work The Dinosaur Heresies, Bakker puts forth the theory that dinosaurs were warm-blooded, his evidence for which includes:

* Almost all animals that walk upright today are warm-blooded, and dinosaurs walked upright.

* The hearts of warm-blooded animals can pump much more effectively than the hearts of cold-blooded animals. Therefore, the giant Brachiosaurus must have had the type of hearts associated with warm-blooded animals, in order to pump blood all the way up to its head.

* Dinosaurs such as Deinonychus led a very active life, which is much more compatible with a warm-blooded animal.

* Some dinosaurs lived in northern latitudes where it would be impossible for cold-blooded dinosaurs to keep warm.

* The rapid rate of speciation and evolution found in dinosaurs is typical of warm blooded animals and atypical of cold blooded animals.

* The predator/prey ratio of predatory dinosaurs to their prey is a signature trait of warm-blooded predators rather than cold-blooded ones.

* Birds are warm-blooded. Birds evolved from dinosaurs, therefore a change to a warm-blooded metabolism must have taken place at some point; there is far more change between dinosaurs and their ancestors, the archosaurs, than between dinosaurs and birds.

* Warm-blooded metabolisms are evolutionary advantages for top predators and large herbivores; if the dinosaurs had not been warm-blooded there should be fossil evidence showing mammals evolving to fill these ecological niches. No such evidence exists; in fact mammals by the end of the Cretaceous had become smaller and smaller from their mammal-like-reptile ancestors.

* Dinosaurs grew rapidly, evidence for which can be found by observing cross-sections of their bones.

Bob, meanwhile, remains a magnet for controversy, as ready as he always has been to challenge the accepted wisdom of past and present paleontologists. Consider the title of his groundbreaking 1986 book, The Dinosaur Heresies. Bob seems to enjoy the role of heretic — especially since he’s often proven right. “I was fond of saying most of dinosaur science was wrong stuff,” Bob notes, “and that did offend a lot of people. … Someone had to say that dinosaurs probably had feathers and well, by gum, they did.”

He was one of the founders of the "dinosaur renaissance", he was extremely focused on the principles that dinosaurs were warm blooded fast and smart! He published his first paper on endothermy. He also was the first to show evidence of dinosaur parental care from the nesting sites of the allosaurus.He was also an adivsor for the film Jurassic Park and he currently serves as the Curator of Paleontology for the Houston Museum of Natural Science.
