• coordinate stated in text
• outcrop-level geographic resolution
When: Macrocephalites macrocephalus ammonoid zone, Mysterious Creek Formation, Early/Lower Callovian (164.7 - 161.2 Ma)
• This species belongs in Callomon's (1984) Cadoceras comma Fauna B8 for the western Cordillera of North America and is Early Callovian in age. Its placement in the L. lilloetensis Fauna B8(c), which is a sub-fauna of Fauna B8 slightly older than Fauna B8(e) (locality 17), agrees well with its stratigraphic position about 10 m beneath locality 17.
