he worked on perfecting his moulding and painting techniques. Today he serves
art and natural history museums by restoring collections or making educational

A 10 foot long, 250 pound Zuniceratops wanders a Cretaceous forest 90 million years ago in what is today New Mexico. . . Like the better known and larger Triceratops, Zuniceratops was a Ceratopsid, a family of four-legged plant-eating dinosaurs characterized by beaks, rows of shearing teeth in the back of the jaw, and elaborate horns and frills. While they resemble defensive shields, the frills are in fact relatively fragile, suggesting that they may have served a purpose other than protecting against a brute force attack. One possibility is that the frills were employed as visual displays in order to intimidate rivals and attract the opposite sex.

Three Ouranosaurus drink at a watering hole while a menacing Sarcosuchus floats nearby 110 million years ago in what is today Africa. The environment is moderately arid with Prickly Juniper and other hardy conifers dominating the ruddy landscape. . Ouranosaurus was a variety of Iguanodont, a group of large plant-eating dinosaurs. At about 24 feet long and 4 tons, Ouranosaurus was unusual in that its skeleton suggests it had a large hump on its back. The hump may have served as a reservoir for water and/or source of nutrition for lean times as they do for modern bison and camels. . Sarcosuchus, a distant relative of the crocodile, was one of the largest giant crocodile-like reptiles that ever lived. 30-40 feet long and weighing 8 to 10 tons, Sarcosuchus was almost twice as long as the modern saltwater crocodile. It would have been a formidable threat even to a beast as large as the Ouranosaurus.

In a scene 75 million years ago from what's now Montana, a six ton male Lambeosaurus rears onto its massive hind legs in response to a possible threat, while a female and juvenile Lambeosaurus drink near the river's edge. Lambeosaurus was a plant-eating dinosaur known for its distinctive hollow cranial crest, which in the best-known species resembled a hatchet. The purpose of the crest is unknown. . Also featured here are Late Cretaceous Period flora including the now extinct tree fern Tempskya and species of flowering Magnolia similar to the Southern Magnolia we know today. Modern birds were just making their appearance, though avian fossils from this period are rare.

In the distance a long-dormant volcano signals its return to activity by cauterizing snowcover into great clouds of steam. Within weeks the volcano will bury this scene beneath a massive ash fall, preserving the remains of the flora and fauna for future exhumation and examination by Homo sapiens 75 million years later.

A ten-foot-long Crichtonsaurus crosses paths with a pair of frogs deep within a Cretaceous forest 95 million years ago. The heavily armored Crichtonsaurus was a herbivore and therefore unlikely to have any interest in frogs as food, while the carnivorous frogs are doubtless in search of smaller prey. The forest is populated with various ferns and the conifer-like Wollemi Pine (not a true conifer, rather an Araucariaceae more closely related to the Monkey Puzzle tree).

An Allosaurus stumbles upon a grazing Stegosaurus in a Jurassic Redwood forest. While it's probable that the 30 foot, 2 ton Allosaurus preyed upon large herbivores, it is doubtful that one would have risked a direct confrontation with an adult Stegosaurus, which could weigh as much as 5 tons and wields a powerful tail tipped with 3-foot spikes. Adding to its survivability, Stegosaurus' front legs may have been strong enough to allow it to pivot and swing its entire backside around to ward off an assault. . In addition to Redwoods and varieties of fern, this Jurassic-period forest includes the now extinct Pachypteris, an arboreal plant that grew to a height of 10 feet and populated every major continent 160 million years ago (in this image, the Stegosaurus is stepping back onto a Pachypteris, obliging a much smaller lizard to abandon its roost). . Was the Allosaurus really striped like Siberian tigers? Fossilized impressions of dinosaur skins reveal combinations of smooth and bony scales, and even feathers for some, but nothing has been preserved that would tell us what colors may have adorned them. Nevertheless, there are plenty of colorful modern reptiles for us to refer to, and birds, which may be the dinosaurs' closest living descendents, are among the most colorful vertebrates of all. Allosaurus reigned for 10 million years, so there was plenty of opportunity for them to evolve a wide variety of coloring schemes, if required.
