TROUSSE DE ROCHES ET DE FOSSILES SIMULES

SIMULATED ROCK AND FOSSIL KIT

Abrégé français

Trousse de paléontologie comportant un fossile simulé et une pierre simulée renfermant le fossile en question. La pierre est constituée d'un matériau composite créé à partir de la combinaison d'un agrégat et d'une matrice de paraffine, matériau qui se fragmente de façon à permettre l'extraction du fossile. Le fossile simulé peut être une représentation d'un fossile de dinosaure, d'une partie d'un dinosaure, d'un oeuf de dinosaure, d'un insecte ou d'une plante ou une sculpture miniature représentant, entre autres, le crâne d'un dinosaure.

Abrégé anglais

A palaeontology kit comprises a simulated fossil, and a simulated rock
encapsulating the simulated fossil. The simulated rock comprises a composite
material that is formed from a combination of an aggregate material and a
paraffin wax matrix material, which composite material is suitable for chipping
away so as to permit excavation of the simulated fossil. The simulated fossil may
comprise a representation of a fossil of a dinosaur, a dinosaur component, a
dinosaur egg, insect or a plant, or a miniature sculpted representation of a fossil
of a dinosaur skull, among other things.
