The Histograms to the left, show the relative abundance of each species, in
the formation i.e. they give some idea of the relative importance of that animal
at a given time period.
The Species names are given at the bottom of the chart for completeness ,
and can be reached by clicking on the pictures.
However, the important point of the diagram is to show the relative importance
of the groups listed below in any given time period.
Brown= Mammal like reptiles
Blue = Rhynchosaurs
Red = Thecodontians
Green = Dinosaur
