I'm one of the few people who never lost their childhood fascination for dinosaurs. Although I have specialized in Marine Biology and Coastal Ecology, I have studied Geology and found it to be the most interesting and absorbing subject. To the point where I study it in my spare time; like a boss.
02’2013. Prenocephale prenes watches over it’s ‘chick’. There is much confusion and debate when Pachycephalosaurids are involved.  Some paleontologists argue that ‘earlier’ Pachycephalosaurids are simply young that have yet to develop their thick-domed skulls. It has been suggested that the genus Homalocephale was the offspring of the genus Prenocephale, asit’s skull has immature sutures the denote infantile qualities. Copyright 2013. All rights reserved.

01’2013. And the first dinosaur of 2013 is the enigmatic Atlasaurus imelakei! Believed to be a close-relative of the Brachiosaurus but with the unusual adaptation of having extended limbs rather than an extended neck.  This raises the question on how this gigantic animal bent down to drink, as it’s neck was proportionally much shorter than that of other sauropods. Atlasaurus hailed from the Jurassic Period and was a relatively early form of sauropod. Copyright 2013. All rights reserved. Rachel Bransgrove.

Goodbye Winter!

It has been an unproductive time for dinosaur drawing. University and work have both taken their toll on this person’s creative brain. But now it’s the non-avain bird’s time to romp; because it was sunny today, and that counts for a lot :)

11’2012. Utahraptor ostrommaysorum was the largest member of Dromaeosauridae family that hailed from the Cretaceous period.  By the end of the Cretaceous, the large Tyrannosaur-like predators were being replaced as the top predator by the swift and smaller Dromaeosaurids.  Though smaller than a T. rex, Utahraptor has still been estimated to reach 11m long.  It is my belief that the larger Dromaeosaurids may have began to loose their feathers; much like the larger Tyrannids, whilst small predators like velociraptor were probably covered entirely.

10’2012. Camarasaurs lentus was an extremely common sauropod from the Jurassic period.  The skeleton is known to have a complicated system of air sacs in order to lighten the weight of the creature.  Obviously I have added a display crest that would have folded against the neck when the specimen was relaxed.  Copyright 2012.  All rights reserved.  Rachel Bransgrove.

Hullo Autumn

New pictures coming soon after a purchase of more nice paper.  I would just like to point out as well that a few of the old images maybe re-visited as some of the aspects maybe incorrect.  E.g Triceratops knees.

06’2012. A Tyrannosaur covers her nest with grasses.  I have always been a believer of the ‘scavenger’ hypothesis when it came to the larger tyrannosaurids.  Tyrannosaurus had front-ways eyes for depth-perception but also possesed a keen sense of smell in order to find a carcass.  I believe that the actual killers of the plains were the smaller tyrannosaurids, such as Albertosaurus, and the dromaeosaurs.  In keeping with the ‘scavenger’ hypothesis, I have made Tyrannosaurus an ugly creature, covered in fleshy nodules and scraggily ‘feathers’ that would have helped to intimidate other predators and drive them away from their kills.  Copyright 2012.  All rights reserved.

06’2012. The heavily-armoured, Sauropelta edwardsorum, from the Early Cretaceous.  I was inspired by my pet Bearded Dragon, who curls her tail when she is intrigued by something nearby.  S. edwardsorum had an unusually long tail for a nodosaurid.

05’2012.  Brachiosaurus inflates it’s nostril display at an out-of-shot adversary whilst Ramphorhynchus catch insects.  The skull of Brachiosaurus has always caused a stir in the paleontological world; mainly due to it’s questionable nasal openings.  After studying the skull myself, I’m inclined to believe that it possessed nasal air sacs that could be filled with air on demand — much like today’s Frigate Birds.  Copyright 2012.  All rights reserved.  Rachel Bransgrove.
