The Galve fossil sites (province of Teruel, Spain) have provided many Mesozoic vertebrate remains. Among these are isolated sauropod dinosaur bones, including one taxon reported only from this locality, Aragosaurus ischiaticus. Here, a new species is named from the Tithonian deposits of the Villar del Arzobispo Formation, of Galve (Teruel province, Spain), Galveosaurus herreroi gen. et sp. nov. It is represented by two humeri, one sternal plate, one ischium, one scapula, one cervical vertebra, one caudal dorsal vertebra, five caudal vertebrae, one Y-shaped chevron and some fragments of ribs. This new species is an eusauropod dinosaur that shows primitive features such as a slightly curved ischium with an unexpanded distal end, amphicoelous vertebrae, neural spine not bifid and an unforked chevron. It appears to be closer to cetiosaurid genera such as Barapasaurus or Cetiosaurus. This new basal sauropod lived at the same time as the eusauropod Lourinhasaurus alenquerensis from Portugal. These are both relict genera that survived in the Iberian Peninsula when more derived neosauropods, such as Losillasaurus or Dinheirosaurus, had taken over other parts of Iberia.

Ceratosaurian theropods evolved in two bursts, first in the Middle and Late Jurassic and then in the Late

The Cameros Basin, distributed over Soria, La Rioja and Burgos provinces in NE Spain, is apparently one of the richest sources of pterosaur footprints, with six ichnospecies of Pteraichnus named to date. The Cameros Basin exposes 9 km thickness of Late Jurassic and Lower Cretaceous continental deposits that are richly fossiliferous. Of the six alloformations in this sequence, the Hué rteles Alloformation is a succession of alluvial siliclastics and lacustrine limestones dated as Tithonian-Berriasian in age. The pterosaur footprints are described, and compared with related forms from elsewhere. Of the six ichnospecies named from the Cameros Basin, Pteraichnus palacieisaenzi and P. cidacoi are nomina dubia because they lack holotypes housed in a public institution. Further, P. manueli and P. vetustior cannot be characterized at present, and so are also regarded as nomina dubia until diagnostic characters may be identified. P. longipodus and P. parvus are probably valid taxa, distinct from P. saltwashensis and P. stokesi, named previously from North America. Of the four supposed pterosaurian ichnogenera, Pteraichnus is valid, and Purbeckopus and Haenamichnus may be valid, but Agadirichnus is a nomen dubium because it is poorly characterized and lacks type specimens.

On August 11 th , 2005 I published a paper in which I described a new genus and species of sauropod dinosaur from the Upper Jurassic-Lower Cretaceous of Galve, Spain: Galveosaurus herreroi. Unfortunately, four months later, a second paper based on the same dinosaur remains was published by different authors. In this second paper, the authors gave the specimens a similar binomial name to the name I gave (with a difference of one letter, an “o”): Galvesaurus herreroi. In that paper, available on-line in pdf format from January 2006, the authors not only ignored my work, but they included a publication date: 1st July, 2005. Nevertheless, the article is included in the issue 15 th of July-December, as could be read in every page of that work. The issue was published on 18 th December 2005, but according to the ICZN code (articles 21 and 23), the date of publication of the Barco et al. (2005) paper should be considered as December 31 st , 2005 and based on the Principle of Priority, the name Galveosaurus herreroi Sánchez-Hernández, 2005 has priority and Galvesaurus herreroi Barco, Canudo, Cuenca-Bescós and Ruíz-Omeñaca, 2005 should be considered as a junior synonym of the former and therefore, an invalid name.
