Taxonomic list

• The relative abundance of each fossil taxon was established in the field by estimating the number of specimens observed in one hour from each richly fossiliferous horizon. The abundance of each taxon was then assigned a code number as follows: (1) 1 to 3 specimens, (2) 4 to 12 specimens, (3) 13 to 50 specimens, (4) 50 to 200 specimens, (5) 200 to 800 specimens, (6)over 800 specimens
