In Depth The superficial morphology of Milleretta is that of a modern lizard with an array of sharp teeth suited for work on insects. Milleretta is considered an anapsid on the basis that the skull has no openings behind the eye socket. Early study of the skull did reveal two depressions at the back of … Read more
In Depth Not many fossilised bones of this dinosaur are known, but those that are are simply huge. Comparing these bones to the more complete remains of other genera has resulted in very rough estimates of around thirty meters long, raising the probability that Ruyangosaurus was one of the largest animals to ever walk the … Read more

We start in England in 1869 when Harry Govier Seeley named Gigantosaurus based upon a few vertebrae, partial limb bones and an osteoderm. … Read more
