Toxaster amplus is an extinct echinoid species which originally lived during the Cretaceous period, dating the fossil specimens to between 145 to 65 millions years old. These fossil specimens are much more typical of those found in Europe and Africa, with a heart shaped thick body. They have been prepped and cleaned so are free of matrix. The morphological features such as shape, and the petal pattern are clearly visible with the naked eye. They were collected in France and come supplied in a packet with an information label with each specimen being approximately 4 cm in diameter.
