The original definition of the ichnospecies Pteraichnus palacieisaenzi
Pascual Arribas and Sanz Pérez (Estudios Geológicos 56:73-100, 2000)
failed to comply with some of the norms proposed in the most recent
version of the ICZN (International code of zoological nomenclature,
fourth edition 1999) for the definition of new taxa. This was an
undesired consequence of the long process of its publication.
Furthermore, the progressive growth of lichens in the tracksite made
it difficult to see the tracks, as a result of which some authors have
called the validity of P. palacieisaenzi into question. After being
completely cleaned, the tracks are of a better quality than at the
time of their discovery, making it possible to describe the characters
of the ichnotaxon in greater detail. Moulds of the type specimens have
been prepared with a view to housing them in a public institution
(Museo Numantino, Soria). The present paper redescribes the
ichnospecies P. palacieisaenzi and compares this ichnotaxon with other
tracks from a variety of pterosaur ichnospecies. Finally, a hypothesis
is proposed on the trackmaker of the ichnospecies.
