I made this model of the bony core of the killing claw for my own interest at the same time as my Utahraptor claw. I used the dimensions from Dr. John Ostroms 1969 description.

I made this model of the bony core of the killing claw as reference for my Utahraptor sculpture. I used the dimensions from Dr. Jim Kirklands paper but I modeled it in a pre-crushed condition.

When Steven Spielberg brought Jurassic Park to the big screen he pumped up Michael Crichton's Velociraptor villains to make them even more terrifying than reality.
Real Velociraptors were about 6 feet long. Soon after that Paleontologist Dr. Jim Kirkland found the real deal in the badlands of Utah. About 18 feet long with a mouth full of sharp serrated teeth, 9 inch retractable killing claws on its feet and 7 inch claws on it's hands, nasty business. Utahraptor lived during the Early Cretaceous about 120 million years ago and probably ate just about anything it wanted.
My sculpture is based on Dr. Kirkland's paper "A Large Dromaeosaur From the Lower Cretaceous of Eastern Utah" and comparisons to specimens of more complete dromaeosaur species. See also: Osteology of Deinonychus antirrhopus..." by John H. Ostrom; "Dromaeosauridae" by John H. Ostrom.

One of the last and largest of the horned dinosaurs.
All Triceratops skeletons displayed to date are composites since no complete specimen has been found. A reasonable estimate for length of an adult would seem to be 26 feet. Skulls have been found with a length of slightly more than 7 feet. Triceratops was a herbivore and would have made a good meal for it's contemporary T.rex. Tooth marks left in fossil Triceratops bones are a good match for T.rex but the debate wages on as to whether or not this was the result of predation or scavenging. Personally I do not think you make an animal as big and nasty as T.rex and tell it to wait around for something to die, but it was probably also an opportunist that would not pass up a free meal!
Much of the information I used to produce this piece came from Dr. Peter Dodson's modern interpretation of ceratopsian data in his book "The Horned Dinosaurs". See also: "A Revision of the Ceratopsia" by Richard Swann Lull ; "The Gigantic Ceratopsidae, or Horned Dinosaurs, of North America" by O.C. Marsh.

What is the biggest predatory dinosaur ever found Tyrannosaurus rex, Giganotosaurus carolinii, or Carcharodontosaurus? So far the scientific jury seems to be out on this one but with a length of 40 feet, six inch dagger-like teeth in a 5-foot head and weighing about 6.5 tons I would still run like heck! Tyrannosaurus rex lived during the Late Cretaceous about 65 - 67 million years ago in western North America. I have based my piece to a great part on the AMNH mounted composite specimen, data from the T.rex "Sue" as well as information from Dr. John Horner's book "The Complete T.rex". The heavier than usual reconstruction of the arms is based on Matt Smith's interpretation of the new material found in Kathy Wankel's T.rex.

Russell; "Skeletal Adaptations of Ornitholestes, Struthiomimus, Tyrannosaurus" by Henry Fairfield Osborn; "Evolution Emerging" by William King Gregory; "Pelvic Musculature of Saurischian Dinosaurs" by Alfred S. Romer.

These are casts of the models I used to create my life-size sculptures for the Canadian Museum of Nature.

This is a cast of the life-size sculpture I created for the Canadian Museum of Nature.
Pteranodon longicepes lived in North America during the Cretaceous about 85 million years ago. This is a model of a male with a wingspan of 24 feet. Fossil evidence shows that they were fish eaters that hunted for their prey in the seas that once covered the middle of the continent. This sculpture was created under the direction of Dr. Steve Cumbaa of the Canadian Museum of Nature.
Key references were Osteology of Pteranodon by G.F. Eaton 1910, Sexual Dimorphism of Pteranodon and other Pterosaurs by S. Christopher Bennett 1992, Pterosauria by Dr. Peter Wellenhofer 1978, Pterosaurs by Wann Langston Scientific American 1981, The Illustrated Encyclopedia of Pterosaurs by Dr. Peter Wellenhofer 1991.

My job was to mold the surviving skull fragments, incorporate the casts of the specimens into a sculpted reconstruction of the skull and lower jaw, mold the finished skull and then cast and paint a finished model of the skull of the Canadian Museum of  Nature under the direction of Dr. Robert B. Holmes. Read the full story.

Final artwork on casts of Chinese feathered dinosaur Sinosauropteryx. 
The Canadian Museum of Nature contracted me to paint two FRP casts of the Chinese feathered dinosaur Sinosauropteryx.  The casts of specimens 127586 & 127587 were provided by the  Canadian Museum of Nature.
Dr. Xiao-Chun Wu provided me with photos of the original fossils and gave the final approval on the artwork.
