Mosasaur 'Marine Dinosaur' Fossil Tooth Group

Comprising two teeth showing good brown enamel, repaired. 67.7 grams total, 45-59 mm
From Morocco, North Africa. From a Cambridgeshire, UK, collection.
The Mosasaur is an extinct, large marine reptile dinosaur with an elongated body, long snout and paddle-like limbs. Found worldwide, they competed with other well-known sea predators of the Late Cretaceous, such as plesiosaurs and ichthyosaurs, for food, existing primarily on a diet of ammonoids, cuttlefish and fish. -
Fossil Knightia Fish in Matrix
Eocene Period, circa 58-36 million years B.P.Sold for (Inc. bp): £91
A Knightia alta fish on a rectangular limestone matrix. 589 grams, 17.8 cm
From a Cambridgeshire, UK, collection.
In southwest Wyoming (and parts of Colorado and Utah) in the Green River Formation are found some of the world's most outstanding specimens of fossil fish. The Green River system was composed of three lakes: Lake Ulinta, Lake Gosiute and Fossil Lake. These Eocene lakes lay in a series of intermountain basins formed by geological events that uplifted the Rocky Mountains during the early Tertiary time. The climate was much different from the desert-like climate of this area today. Both the fauna (crocodiles, alligators, boa constrictors and some subtropical fish families) and the flora (such as large palm trees) indicate a climate much like that found along the Gulf Coast today. Large amounts of ash found in the sediments indicate that volcanoes were particularly active at this time. -
