This collection is from the same sequence as collection shipped earlier (July, 1968) from the Reindeer Hills. These are a sequence of argillites, cherts and limestones. Generally Mesozoic, Jurassic-Cretaceous, overlain by Cantwell Fm, Cretaceous system. -- Samples were dissolved in acetic acid and the insoluble residues examined for conodonts. |

| Comment: | No conodonts found. Referring to the composite fauna found in samples 68AMr163A-G: Panderodus ranges from Ordovician to Devonian and S. exiguus was described from the Emsian of Australia. This identification is exceedingly questionable since it is based on a single broken specimen. A Silurian or Devonian age for these rocks is indicated and a Devonian age is suggested. |

The identified material is being retained for our reference collections. Samples of each collection will be etched for conodonts and another report will forllow if any are found. Additional parts of collections will be discard after this work is done unless you instruct us otherwise. |

| Comment: | All 7 collections are Silurian or Devonian in age but none of the identified forms are well-enough known to narrow down this range. There is a variety of forms represented in several of the collections and if taken together, this would suggest a Devonian age is more likely than Silurian. |
