Also known as South Joggins; Coal Measures; Head of Bay of Fundy
Where: Nova Scotia, Canada (45.7° N, 64.5° W: paleocoordinates 8.0° S, 7.2° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Joggins Formation (Cumberland Group), Westphalian A (318.7 - 316.9 Ma)
• From Steen (1934): "top of the Joggins formation...Division 4, Section XV., Coal-group 15 of the Joggins section given in Dawson's 'Acadian Geology,' 1868, pp. 156-178." From Lyell (1853): The fossils are from Bed 5 of a 25 ft section, composed of 7 beds. Bed 5 is approximately 600 ft below the main coal, "King's Vein".
•Original entry for Local Section name was "South Joggins"; for Bed/horizon "bed 5". In Steen (1934) a "bed 5" is not mentioned in any way. Also, in papers published before and after Lyell's "On the Remains of a Reptile..." (1953) a different numbering is applied to the Joggins Section. Thus, it is more appropriate to follow the stratigraphic terminology used in Dawson (1878, Acadian Geology, 3rd edn.; 1882, Phil. Trans. R. Soc. Lond., 173), Steen (1934, see description above) and Carroll (1964). Coal-group 15 consists of 3 beds with a total thickness of 10 ft 6 in. (Dawson, 1878) (TL)
•Original entry for chronostratigraphy was simply "Westphalian". Currently, the Cumberland Group is considered eqivalent to Westphalian A (Langsettian) (see e. g. Holmes et al., 1989, J. Vert. Paleont. 19; or Falcon-Lang et al. 2006, J. Geol. Soc. Lond. 163).(TL)

Taxonomic list
•
•All catalogue numbers are from Steen (1934) and/or from Carroll (1967).
•
•The taxon "Batrachoididae indet.", entered under the reference Lyell & Dawson (1853), has been removed from the taxonomic list for it is a family of teleost fish. It probably referred to the "batrachian" affinities of the tetrapod bones noticed by Wyman (1853) but all these bones finally were assigned to Dendrerpeton acadianum n. gen. et sp. (see pls. II and III in Lyell & Dawson/Wyman/Owen, 1853). Thus the originally enterd taxon "Dendrerpeton acadianum", reference: Lyell & Dawson, was replaced by "Batrachia indet.", reference: Wyman (1853), and re-identification by Owen (1853) was added (TL).
•Re-identification of "Dendrerpeton oweni n. sp." as "Dendrerpeton acadianum" by by Steen was removed after opinons on synonymy of the the former with the latter species were entered into the database (TL).

•? Poacites sp. of Lyell and Dawson not entered, because that taxon is a grass.
