[D] Nopcsaspondylus alarconensis [sG] [T]
Cretaceous Late Coniacian
Saurischia Sauropodomorpha Sauropoda Titanosauria
Candeleros Formation (presumably), Argentina
Represented by a complete mid to posterior dorsal vertebra,with centrumand neural arch separated. The small centrum and large pleurocoel suggest that they derive from the same vertebra, as this is a common feature in rebbachisauroids.
Diplodocoid sauropod characterized by mid to posterior dorsal vertebrae with very reduced centra, forked medial centropostzygapophyseal lamina, lateral lamina of the neural spine formed by the spinodiapophyseal lamina plus a lateral spinopostzygapophyseal (different from that forming the postspinal lamina).
Nopcsa, referring the researcher that first studied this material; spondylus, Gr. vertebra. referring to Barda Alarcón, the original locality where from it was collected by the end of 19th century.
