Coelurosauravus (meaning “hollow lizard grandfather”) by Alain Bénéteau:
“This is the cover illustration of the book I’m finishing. Coelurosauravus is a perfect critter to illustrate the diversity of time before dinosaurs. For more info about the book on sale in march 2009 please see my website paleospot”
Rat snakes are mid-sized or larger constrictors that are found primarily in the northern hemisphere. They may occupy top levels of the food chain, seeing as they eat rodents and birds and can grow up to 3 m (10 ft) long. These reptiles have become extremely popular as pets, even though sometimes they tend to be skittish and even aggressive. Their bites are, for the most part, not too serious, and produce no threat to humans. Originally thought to be nonvenomous, scientists have discovered very faint traces of venom in Old World species, but it is not enough to even harm a human.
