“…1), has a total area of 5,665 km 2 , with 42% used as agricultural land (PEI Department of Agriculture and Fisheries 2015). The structural trend of the island is southwest-northeast (Whiteside 1965;van de Poll 1989), and PEI is characterized by a moderate or humid temperate climate strongly influenced by winds, air masses, and weather systems that move east from the mainland. January and July mean temperatures are −7 and 18.7 °C, respectively, with an annual mean precipitation of 1100 mm (25% as snow).…”

“…The dominant soil order is Podzolic/Spodosols (Fig. 2); soils in this order formed from the soft, red sandstone bedrock, are sandy, mostly red in colour, and low in bases and nutrients, and present an acid reaction (van de Poll 1989). Other soil orders, including Gleysolic/Gelisols, Luvisolic/Alfisols, and Brunisolic/Inceptisols, are also present (Fig.…”

“…(c) Locality and horizon ROM 55402 was collected from a locality at Cape Egmont in southwestern Prince Edward Island, Canada. The Egmont Bay Formation crops out along the western part of the island, and is regarded to be latest Pennsylvanian (Stephanian) in geological age on the basis of plant body fossils and pollen [21]. Thus, the fossil is Gzhelian in age (303.7 to 298.9 Ma) [22].…”

“…The base of the tail forms a tightly articulated series up to, and including, caudal 20, and there is an articulated series of 13 distal caudals preserved adjacent to presacrals [19][20][21][22][23][24][25]. If the latter series is preserved in normal position with respect to the proximal articulated series (i.e.…”

The oldest parareptile and the early diversification of reptiles

et al. 2015

Amniotes, tetrapods that evolved the cleidoic egg and thus independence from aquatic larval stages, appeared ca 314 Ma during the Coal Age. The rapid diversification of amniotes and other tetrapods over the course of the Late Carboniferous period was recently attributed to the fragmentation of coalswamp rainforests ca 307 Ma. However, the amniote fossil record during the Carboniferous is relatively sparse, with ca 33% of the diversity represented by single specimens for each species. We describe here a new species of reptilian amniote that was collected from uppermost Carboniferous rocks of Prince Edward Island, Canada. Erpetonyx arsenaultorum gen. et sp. nov. is a new parareptile distinguished by 29 presacral vertebrae and autapomorphies of the carpus. Phylogenetic analyses of parareptiles reveal E. arsenaultorum as the closest relative of bolosaurids. Stratigraphic calibration of our results indicates that parareptiles began their evolutionary radiation before the close of the Carboniferous Period, and that the diversity of end-Carboniferous reptiles is 80% greater than suggested by previous work. Latest Carboniferous reptiles were still half as diverse as synapsid amniotes, a disparity that may be attributable to preservational biases, to collecting biases, to the origin of herbivory in tetrapods or any combination of these factors.

“…1). The tracks occur as natural casts within redbeds of the Hillsborough River Formation (van de Poll 1989). The trackway-bearing horizon occurs as a locally reduced, pale grey sandstone horizon within a sequence of tabular, reddish brown sandstone beds with internal large-scale, shallow crosssets and less commonly, narrow troughs (Fig.…”

The fi rst fossil tetrapod footprints that were discovered on Prince Edward Island, and which were previously undescribed, are small reptilian trackways assignable to the ichnogenera Notalacerta and Gilmoreichnus. Their closest zoological correlatives are small, Permo-Carboniferous "stem-reptiles" of the families Protorothyrididae and Captorhinidae in the suborder Captorhinomorpha, and pelycosauran reptiles, possibly of the Ophiacodontidae. Reptiles of this type are rare to unrepresented in the skeletal fauna of the province. The biochronology of the track-bearing bed, combined with terrestrial vertebrate, palynological and macrofl oral records, suggest that the host Pictou Group redbeds on Prince Edward Island young from late Stephanian (Pennsylvanian) at Malpeque Bay to early Permian in the north. The combined discoveries of tetrapod footprints and trackways from these Permo-Carboniferous redbeds suggests that the record is potentially extensive. Now included in this record is the youngest known occurrence of the ichnogenus Notalacerta. RÉSUMÉLes premières empreintes de fossiles de tétrapodes découvertes sur l'Île-du-Prince-Édouard, et précédemment non décrites, sont des traces d'un petit reptile qu'on peut rattacher aux ichnogenres Notalacerta et Gilmoreichnus. Leurs parents géologiques les plus proches sont les petits " reptiles-tiges » permocarbonifères des familles des protorothyridides et des captorhinides du sous-ordre des captorhinomorphes, ainsi que les reptiles pélicosauriens, possiblement les ophiacodontides. Les reptiles de ce type sont rares sinon absents au sein de la faune squelettique de la province. La biochronologie des strates renfermant des traces conjuguée aux relevés de vertébrés terrestres et aux relevés palynologiques et macrofl oraux laisse supposer que les couches rouges hôtes du groupe de Pictou, sur l'Île-du-Prince-Éd-ouard, remontent à la période du Stéphanien tardif (Pennsylvanien), dans la baie Malpeque, au Permien précoce, dans le nord. Les découvertes combinées d'empreintes et de traces de tétrapodes des couches rouges permocarbonifères semblent indiquer que la quantité d'enregistrements pourrait être vaste. Ces enregistrements comprennent désormais la manifestation la plus récente connue de l'ichnogenre Notalacerta.
