Brontosaurus prey In 2012 CollectA was the first company to introduce an innovative series entitled Dinosaur Prey to complement its carnivorous dinosaurs, and this year we add a figure of a dead Brontosaurus to the range. As with all models in the series it shows wounds that either can be traced through the fossil record or are likely to have been made by a predator and have led to the animal's eventual collapse. The new model depicts the Late Jurassic sauropod Brontosaurus that lived 157 - 145 million years ago in an ungainly state of collapse.
