Zby atlanticus

When Octávio Mateus discovered a haul of massive sauropod fossils in western Portugal in 1996, the suspiciously familiar features at both ends of a radius and the heart-shaped crown of a single tooth prompted him to assign them to the roughly same-aged Spanish colossus Turiasaurus riodevensis, albeit with some reservation. Closer inspection revealed grooves, compressions, and bulges in the forelimb of Turiasaurus that were absent in the new specimen while the new forelimb sported flanges, ridges and an unusual oblong-shaped claw that was absent in Turiasaurus. Although a like for like comparison of other bones has been hampered by the fact that, well, no other like for like bones have been found for comparison, the differences as mentioned are significant.

In 2014 Mateus, Mannion and Upchurch severed the Portuguese remains from the critter they had been assigned to for the best part of two decades and named them Zby atlanticus, in honor of George Zbyszewski and the lovely little bay on the Atlantic coast where they were discovered. But it's still closely related to Turiasaurus and thus a member of Turiasauria; a group of large-bodied, plant-munching sauropods whose members have yet to be found outside of Europe.
(Zby of the Atlantic)Etymology
Zby is a hypocorism (a pet name or nickname) derived from the surname of Polish-French paleontologist George Zbyszewski, who devoted his career to the geology and paleontology of Portugal. The species epithet, atlanticus, means "atlantic" in Latin, because the specimen was found on the coast of central west Portugal in a scenic bay overlooking the Atlantic Ocean.
Discovery
The remains of Zby were discovered in the Amoreira-Porto Novo Member of the Lourinhã Formation at Vale Pombas, Lourinhã municipality, central west Portugal, by Octavio Mateus in 1996.
The holotype (ML 368) is a partial skeleton including a complete tooth with root, a fragment of cervical (neck vertebra) neural arch, a chevron, an almost complete right shoulder girdle, and a right forelimb including the humerus (upper arm), radius and ulna (forearm), three metacarpals (I, III, and IV), and three finger bones (phalanges I-1, I-2, and II(?)-1).
