Remarks
Originally described as Pentamerella papilionensis by Hall in 1858. However, it is almost invariably referred to as Pentamerella pavilionensis or Pentamerella pavillionensis in literature with the presumption that it is derived from Pavilion, NY where indeed it is common in the Jaycox Member. Because of its widespread usage we retain the name Pentamerella pavilionensis here.
From Wilson (2014, p. 104): “Medium-sized, inflated, broadly ovate shell. Surface finely punctate, marked by rounded or subangular plications and fine growth lines. Similar to P. arata, but generally with fewer plications and found in different stratigraphic unit. To 25-30 mm.”
From Carlton Brett and Gordon Baird: “Pentamerella pavilionensis first appears in carbonate platform stocks in the Eifelian and is reported from all limestones of this age. This brachiopod found is diagnostic of and widespread in high diversity, often coral dominated assemblages in calcareous mudstone and limestones in western New York and many mid-continent localities. Overall pentamerids appear to have thrived in warm water carbonate facies and to be excluded from deeper siliciclastic settings. There are a number of species of pentamerids in the coral rich Michigan Basin units.”
