LDC-185.0, Little Dantzic Cove [Chapel Island Fm] (Cambrian of Canada)

Also known as SSF 65.16

Where: Newfoundland and Labrador, Canada (47.0° N, 56.0° W: paleocoordinates 82.4° S, 51.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Chapel Island Formation, Tommotian (525.5 - 521.0 Ma)

• STRATIGRAPHIC RELATIONS: From Member 4 of the Chapel Island Fm, which overlies the Renconte Fm, and is overlain by the Random Fm. AGE: Unclear from Landing et al. (1989), who refers to this as post-Nemakit-Daldynian and pre-Tommotian; Wasonella crosbyi zone; here placed in Tommotian, until clearer data are available. STRATIGRAPHIC POSITION: From the Wasonella crosbyi zone, near the middle of the regional section, at 185.0 m, near middle of Member 4.

• bed-level stratigraphic resolution

Environment/lithology: peritidal; lithified, oncoidal limestone

• ENVIRONMENT: Peritidal.
• SPECIFIC LITHOLOGY: Bedded limestones with oncolites and mud-cracked stromatolitic laminae. LITHIFICATION: Lithified, on the basis of facies description and preparation techniques.

Size classes: macrofossils, mesofossils, microfossils

Preservation: concretion, replaced with phosphate

Reposited in the ROM

Collection methods: bulk, surface (in situ), chemical,

• COLLECTOR: Not stated, but presumably Landing et al. REPOSITORY: Royal Ontario Museum (ROM).
