Spiriferides, Ponta Grossa Fmn., Sao Domingos Mbr., Parana Basin (Devonian to of Brazil)

Where: Parana, Brazil (25.0° S, 50.0° W: paleocoordinates 84.8° S, 102.1° W)

• coordinate estimated from map

• basin-level geographic resolution

When: Sao Domingos Member (Ponta Grossa Formation), Eifelian to Eifelian (393.3 - 372.2 Ma)

• Members of Ponta Grossa Fm., from bottom to top, are Jaguariaiva, Tibagi, and Sao Domingos. Melo (ref. 9944) restricts the name "Ponta Grossa" to "the lower, richly fossiliferous transgressive shaly section of the Devonian in the Apucarana Sub-basin, the name Jaguariaiva being regarded as a junior synonym...The Ponta Grossa and Sao Domingos shales are interpreted to be units of equal lithostratigraphic rank...The Tibaji "Sandstone" (in fact more silty than sandy) should be kept as a subordinate unit of the Ponta Grossa shale due to its restricted distribution...The Ponta Grossa Shale is well known for its abundant marine invertebrate fauna of Emsian/early Eifelian age, first described by Clarke (1913)..." Age range from Morsch (ref. 9945).

• member-level stratigraphic resolution

Environment/lithology: marine; black, gray shale and sandstone

• Melo (ref. 9944): Ponta Grossa shale proper is transgressive; Tibaji and Sao Domingos probably regressive; uppermost Sao Domingos transgressive.
• [rough translation]: "gray to black shales, siltstones, fine sandsontes, and conglomerates"
