“…After the Campanian, most (14 of 16) records of “macrobaenids” are from the latest Cretaceous and early Paleocene of North America, so it is possible that the late Paleocene records in Europe and Asia represent a reinvasion from North America. Intercontinental dispersal of turtles via high latitude dispersal routes, including from North America to Europe, was common during the late Paleocene because of high global temperatures at this time (Godinot & Lapparent de Broin, 2003; Holroyd et al, 2001; Holroyd & Hutchison, 2000; Joyce et al, 2023). More research on the phylogenetic relationships of North American and Old World “macrobaenids” is needed to test this hypothesis.…”

The abundant record of marine turtles from the Late Cretaceous of Appalachia contrasts with the relatively poor record of contemporaneous terrestrial and freshwater species. A new taxon from the Santonian‐Campanian of Alabama, Appalachemys ebersolei gen. et sp. nov., is described here and assigned to a grade of freshwater turtles known as “macrobaenids.” Appalachemys can be differentiated from other “macrobaenids” by the presence of a nearly round carapace, deep nuchal emargination, and nine pairs of costals. With a carapace more than 80 cm in length, Appalachemys is among the largest freshwater turtles to ever inhabit North America. The absence of pre‐Campanian “macrobaenids” from Laramidia indicates that the North American distribution of this grade may have been restricted to Appalachia prior to the recession of the Western Interior Seaway. Phylogenetic analysis places Appalachemys as the sister taxon to all post‐Santonian “macrobaenids.” Although the phylogeny lacks statistical support, it demonstrates morphological similarities between the K/Pg boundary species Osteopygis emarginatus and Maastrichtian‐Danian species referred to Judithemys. We, therefore, refer all but the Campanian type species of Judithemys to the genus Osteopygis. A review of all North American “macrobaenid” occurrences reveals that despite originating in Asia, the record of the grade (as defined here) is predominantly North American. Future studies can test whether late Paleocene records in Asia and Europe resulted from dispersal from North America.

With their particular body plan within amniotes and their amazing fossil record, turtles represent a great interest for both neontologists and paleontologists with a strong anatomical background. The Turtle Evolution Symposia are regular international meetings that gather scientists working with different aspects related to the evolutionary history of turtles, from their origin and early evolution until recent times. The latest edition of the Turtle Evolution Symposium was organized in 2021 amidst the COVID-19 outbreak and held virtually from the facilities of the Museo Paleontol ogico Egidio Feruglio in Trelew (Patagonia, Chubut, Argentina). More than 75 scientists from 25 countries presented their latest advances on topics related to turtle evolution, some of which are published in this Special Volume of The Anatomical Record. Both the Turtle Evolution Symposium 2021 and this Special Volume are dedicated to Marcelo S. de la Fuente who was the first researcher who specialized in the study of extinct turtles in South America, and his studies have an important regional and international impact.
