alb3885935 During the late Jurassic period, Europe was a dry, tropical archipelago. In this image Archaeopteryx is depicted near the shore of the Tethys Sea. The Archaeopteryx is the earliest known example of a fully feathered dinosaur. Despite its resemblance to birds, Archaeopteryx has more in common with small dinosaurs, especially in regard to its clawed arms and tiny teeth. The highly evolved feathers may have permitted Archaeopteryx to glide short distances, however, it's unlikely Archaeopteryx could fly like a bird.

Mosasaurs in general are not dinosaurs but literally lizards adapted to an aquatic environment. It is believed they are related to modern monitor lizards such as the Nile Monitor and Komodo Dragon.

alb5579001 Rajasaurus in the Lameta Formation of Western India. Titanosaurus graze in the background.. Rajasaurus was found in the Lameta Formation in western India in what is now the Narmada River Valley. Dated to 72-66 million years ago, Lameta was forested and had some river systems. India at this time was a large island making its way north to collide with central Asia/China.. From some skull remains and a few other remains and fragments Rajasaurus is determined to be an Abelisaur not distantly related to Majungasaurus. Lack of remains hamper size estimates which range from 22 feet and barely 2 tons to 34 feet and over 3 tons. Here it is depicted with some speculative tiger striping.. It shared the landscape with many animals including the medium sized sauropod Titanosaurus. They are estimated at about 40 feet long and maybe 13 tons.

Midway back and to the left are Parasaurolophus tubicen. A fair sized Hadrosaur they might be as big as 36 feet and 5 tons. A full sized adult would prove a challenge for the local predator.

An area the size of the Sahara was a vast wetland and river system. One of the top land predators was Carcharodontosaurus with an estimated length of 40-44 feet and weight 7-8 tons and knife blade like teeth. One of its likely prey was the Iguanodont Ouranosaurus. Fairly large at 23-27 feet long and 4-5 tons in weight, but small enough that it could be taken down fairly easily by a large Carcharodontosaurus.
