Keichousaurus fossils
Middle Triassic age, Guanling Formation, Xingyi, Guizhou, China.
The matrix is a compacted mix of fine volcanic ash, silt and is intersected by natural calcite mineral formations.
Fossil has NO restoration, carving, resin, fillers, adhesives, paint or highlighting.
This very rare dorsal (skull uppermost) presentation of a FEMALE JUVENILE, has been extremely skilfully prepared.
Colour variation amongst the bones are the result of fossilization & an artifact of preparation (method of removing matrix to expose bones).
Testing conclusively proves the bones are genuine.
Matrix has repair - the slate usually fractures on excavation - white lines are natural calcite mineral veining - the matrix has been tested & proves genuine.
The lighter areas of matrix are the result of exposing an underlying layer of matrix & is NOT of artificial material.
