 Many of her discoveries would be described scientifically by the geologists William Conybeare, Henry De la Beche, and William Buckland.It was Anning who observed that stony objects known as "bezoar stones" were often found in the abdominal region of ichthyosaur skeletons, and she noted that if such stones were broken open they often contained fossilized fish bones and scales as well as sometimes bones from small ichthyosaurs.This led her to suggest to Buckland that they were fossilized feces, which he named coprolites, and which he used to better understand ancient food chains.. Mary Anning made many fossil discoveries that revolutionized science.
