Phylogeny of the Late Paleozoic superfamily Adrianitoidea Schindewolf (Ammonoidea)

The age of North America’s youngest Paleozoic continental vertebrates: a review of data from the Middle Permian Pease River (Texas) and El Reno (Oklahoma) Groups

“…Because the past 20 years have seen considerable research on Permian ammonoids (e.g. Leonova, 2002Leonova, , 2007Leonova, , 2011Leonova, , 2018Furnish et al, 2009;Leonova and Boiko, 2015;Zhou, 2017), it is appropriate to revisit Clifton's taxa (Table 1) and compare their stratigraphic ranges at the generic level (Table 2).…”

“…The species was transferred to Metacrimites Ruzhencev, 1950(Leonova, 2002, which was later synonymized with Neocrimites Ruzhencev, 1940(Furnish et al, 2009. Because this synonymy was addressed and rejected by Leonova and Boiko (2015), the genus Metacrimites is used here even though Zhou (2017) followed Furnish et al (2009) In summary, of the seven ammonoid genera considered above, three are known from Cisuralian and Guadalupian deposits, two are reported to extent from the Cisuralian to Lopingian, and two are recorded in Guadalupian to lower Lopingian rocks (Table 2). This broad stratigraphic distribution refutes frequent and emphatic claims that ammonoid data relegate the Blaine Formation to the Leonardian, Kungurian, Cisuralian, or Lower Permian (Lucas, 2002b(Lucas, , 2004(Lucas, , 2005a(Lucas, , 2013(Lucas, , 2017Lucas and Golubev, 2019).…”

Permian basinal ammonoid sequence in Nanpanjiang area of South China—possible overlap between basinal Guadalupian and platform-based Lopingian

“…The sutural of the new genus is close to the ancestor Neocrimites , but increasing 1–4 or more umbilically derived lobes, while the most identified character, the W/D value of the new genus, is always larger than 1.0, although in a few cases the value of Neocrimites may reach to 1.19 (Leonova and Boiko, 2015). In genus Crimites , C .…”
