All fossils listed in this Research Bulletin are available for inspection on request at the Artifact Repository maintained by the Petun Research Institute. A random examination of some of the collections in the care of the Petun Research Institute resulted in the following specimens being noted and here listed by site and designation. While only a small percentage of the total sample available was examined, the repetitiveness within the sample suggests it is probably representative of the whole. All fossils examined were in their natural condition, none are modified by human agency. The fossils are usually minimal fragments only, sometimes impressions in a matrix of sandstone, shale, or limestone.
Measurements are approximate.
