On the validity of Pteraichnus palacieisaenzi, Pascual Arribas and Sanz Pérez 2000: new data from the Huérteles formation

Bringing Together Research, Geoconservation and Reaching a Broad Public in the Form of a Geotourism Project: the Ichnite Route of Soria (Spain)

“…The great amount of literature that has appeared has led to the description of tracks from different groups of dinosaurs ( Fig.2), such as theropods (Lockley et al 1998;Barco et al 2004, Hernández Medrano et al 2006 In addition, crocodyliform Pascual Arribas et al 2005) and turtle tracks (Fuentes Vidarte et al 2003;Pascual-Arribas and Hernández-Medrano 2015) have been described. One of the most significant features of the footprint record is thus the large number of different types of footprint preserved (the ichnodiversity).…”

“…E) Ornithopod trackway in the tracksite of Santa Cruz. F) Large pes pterosaur track (Pteraichnus palacieisaenzi, Pascual-Arribas et al 2015) in the tracksite of Los Tormos. G) Small manus-pes pterosaur track set (Pteraichnus) Pascual Arribas and Hernández Medrano, 2012).…”

“…However, the museum also preserves a large collection of vertebrate tracks collected from different outcrops from the Huérteles Formation in the Highlands of Soria indeed, the collection has more than 70 slabs. -2011/19-b) assigned to Pteraichnus palacieisaenzi from tracksite of Serrantes (Pascual-Arribas et al 2015). E) Tiny theropod track (MNS2005-111-4A) assigned to Kalohipus bretunensis from the tracksite of Valdehijuelos (Pascual-Arribas and Hernández-Medrano, 2011;Castanera et al 2015).…”

“…In terms of heritage, their value is particularly considerable given the low number of ichnotaxa (and footprints) that have been described from either group worldwide (Avanzini et al 2005;Lockley et al 2010). In addition, the collection houses a great number of slabs with pterosaur tracks, some of which are holotypes of ichnospecies assigned to the ichnogenus Pteraichnus (see reviews in Sánchez-Hernández et al 2009;Pascual-Arribas et al 2015). It includes the holotypes of P. parvus, P. longipodus (Fig.…”

“…There are also tracks belonging to the ichnospecies P. palacieisaenzi (Fig. 4D), the holotype of which is preserved at the Los Tormos tracksite (Pascual-Arribas et al 2015) and tracks assigned to P. cf. stokesi (Pascual-Arribas and Hernández-Medrano, 2016).…”
