The Carcharodontosaurus saharicus was one of the largest predators (larger than its distant North American T-Rex cousin) of all time and is also related to Allosaurus and the South American Giganotosaurus. The Spinosaurus was both a beachcomber type scavenger and an active hunter taking small stranded Plesiosaurs, Pterosaurs, turtles and large fish.

Acquired between the 1970s and 1980s. From the private collection of John Watson, Cambridge, UK.

Dinosaur eggs are known from about 200 sites around the world, the majority in Asia and mostly in terrestrial (non-marine) rocks of the Cretaceous Period. It may be that thick calcite eggshells evolved during the Cretaceous (145 to 65 million years ago). Most dinosaur eggs have one of two forms of eggshell that are distinct from the shells of related modern animal groups, such as turtles or birds; however, some eggs closely resemble the type of shells seen in present day ostrich eggs.

Comprising: a cut and polished agate geode section, a polished fluorite dish, pyrite, smoky quartz, quartz, amethyst, and others. 1.46 kg total, 1.6-14.1 cm
