GSC C-8234. Romundina type-locality (Devonian of Canada)

Also known as Locality 10 of Smith 1980

Where: Nunavut, Canada (73.4° N, 101.3° W)

• Paleocoordinates: 4.4° N, 71.7° W (Wright 2013)

• coordinate based on nearby landmark

When: Ozarkodina eurekaensis - Ancyrodelloides delta conodont zone, Lower Member (Drake Bay Formation), Early/Lower Lochkovian (419.2 - 416.2 Ma)

• Märss et al. (2006) note that it is Drake Bay formation, Ozarkodina eurekaensis or Ancyrodelloides delta zone. (There is a joint Ozarkodina eurekaensis - Ancyrodelloides delta zone...) Oddly, they state that Sophialepis is named for the Sophia Lake formation and attribute the type to that (p. 115); however, on the very next page, they state the the type locality is the Drake Bay formation. Drake Bay is repeated in the figure caption (p. 104). Elliot et al (2015) make this an unnamed lower member.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified limestone

Size class: macrofossils
