Tyrannosaurus Rex Tooth in Fossil Matrix
About the Item
Tyrannosaurus Rex Tooth in Fossil Matrix.
Late Cretaceous, circa 65 Million years before present.
Lance Formation, Marchant Ranch Quarry, Niobrara County, Wyoming. Collected under lease by Western Paleo of Salt Lake City in 1992.
An incredibly rich fossil matrix, with a large Tyrannosaurus rex tooth surrounded by the jumbled remains of two herbivorous dinosaurs, Edmontosaurus and Ankylosaurus, as well as several other terrestrial and aquatic animals. An aesthetic presentation preserving a cross-section of life immediately preceding the extinction event that killed the dinosaurs.
Found in the Lance Formation in the western USA, this fossil matrix gives an incredible insight into the creatures that roamed the earth at the end of the Late Cretaceous period. Most prominently displayed is the tooth of a near adult sized Tyrannosaurus rex, with its immaculately preserved serrated edges. This tooth would have come from the back half of the T. rex jaw - a jaw which, at the height of adulthood, would have held over 60 such saw-edged teeth and was easily capable of crushing bone. The matrix has also captured the teeth and numerous parts of ossified tendons from one or possibly several hadrosaurs (duck-billed dinosaurs), most likely Edmontosaurus. A large piece of bone at the base of the block is likely the scapula, or shoulder blade of an Edmontosaurus. On the reverse, there is a worn tooth from an ankylosaur (the armoured dinosaurs), probably belonging to an Ankylosaurus.
Beyond the dinosaurs, other animals are also present. In the centre of the block, there is part of the left jaw of a small mammal bearing a molar, as well as multiple fragments of terrapin plastron (the bottom side of the shell that lies beneath the abdomen). One has a stippled surface, displaying the outside texture of the plastron, whereas another is turned over so the smooth side is visible. The matrix also bears a single, small crocodile tooth, as well as several enamel-covered scales from gar fish and other aquatic creatures.
These fossilised specimens are held together by a mixture of sand, mud, and pebbles which is likely the result of a fluvial process, as is the case for almost all dinosaur fossils from the Hell Creek and Lance Formations. These creatures most likely died on a floodplain, where flood waters later washed them downstream into a high energy environment, before they settled and were buried. This resulted in the preservation of land animals alongside freshwater creatures.
Providing a rich and varied summary of life 65 million years ago, this matrix displays the remnants of at least three dinosaurs, a mammal, a turtle, a crocodile, and multiple fish. A remarkable artefact offering an incredible insight into life at the end of the reign of the dinosaurs.

- Natural Gogotte FormationLocated in London, GB'Louis XIV' Gogotte Formation Measures: circa 30 Million y/o 105 x 76 x 15 cm A magnificent example of a gogotte formation, nicknamed Louis XIV, composed of thick swirls and folds of sparkling sandstone. Discovered in the Oligocene sand dunes of Fontainebleau, France, formed circa 30 million years before present or later. The incredible, almost otherworldly appearance of gogottes may easily be mistaken for the work of a most talented artist. In fact, these sandstone sculptures are entirely natural in origin. They have been found in multiple locations but those from Fontainebleau, such as the present example, are the most remarkable. Thirty-five million years ago, a sea covered what is now the forest of Fontainebleau, and dunes of exceptionally fine and homogenous sand formed. As silica-rich water filtered through this sand, it turned into stone. The flow of water finely modelled the sandstone into the forms we now know as gogottes. These are rare and are only found sporadically, several metres buried underground. They owe their sparkling white appearance to the extreme and unmatched purity of the Fontainebleau sand, sometimes reaching a composition of 99.9% silica. Each of them is unique – a masterpiece slowly fashioned by the hands of Nature. The name “gogotte” was coined by French geologist Claude Guillemin (1923- 1994), inspired by the children’s book series Babar the Elephant...Category
