Figure 1.11   Composition of a Middle Jurassic vertebrate fauna from England. The proportions of the major groups of vertebrates in the fauna are shown as a pie chart (a). The sample can be divided into categories also of bone types (b) and taphonomic classes (c), which refl ect the amount of transport. Dimensions of theropod dinosaur teeth show two frequency polygons (d) that are statistically signifi cantly different (t-test), and hence indicate two separate forms.
