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.

From an old Lincolnshire, UK, collection. Property of a West Northamptonshire, UK, gentleman.

The mammoth lineage branched from the Asian elephant around 6 million years ago, and later on, the Woolly Mammoth, Mammuthus primigenius, evolved in eastern Siberia. Woolly mammoths, being slightly smaller than living African elephants, were foragers and ate grass, as well as small, nutritious flowering plants that flourished in the environment where they lived. They may also have used their curved tusks to dig through snow and eat plants that other foragers were unable to reach.

A Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 155 grams, 10.2 cm



From a Cambridgeshire, UK, collection.

Carcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on the structuring of the marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 metres (52 ft) and also affirm that it had a cosmopolitan distribution. Scientists suggest that in life it looked like a stockier version of the great white shark, Carcharodon carcharias.
