Teinurosaurus sauvagei

Despite being represented by just a single, elongate tail vertebra from the Jurassic of Portugal, the "Stretched tail lizard" has led an awful eventful life after death. It was discovered loitering in the Musée Géologique du Boulonnais at Boulogne-sur-Mer in 1897 by French paleontologist Henri-Émile Sauvage who promptly assigned it to Iguandon prestwichii, which had already been renamed Cumnoria prestwichi (with one less "i") by Seeley in 1888 and reassigned to Camptosaurus prestwichii by Lydekker in 1889. Sauvage semi-caught-up in his very last scientific publication—cataloguing the Jurassic reptiles of Bologne in France—at the ripe old age of 72 in 1914, when he called this troublesome vertebra Cumnoria aff. prestwichi, presumably forgetting it was Portuguese! Then Franz Nopcsa identified it as the property of an ostrich-like theropod that he initially referred to as Teinourosaurus in 1924 and officially christened Teinurosaurus (with one less "o") in 1928.

The new name was almost lost when a footnote announcing this news was placed alongside a citation of Saurornithoides by a clumsy printer instead, and a correction in the following years issue was completely missed by Friedrich von Huene who (1) thought that Nopcsa had intended to rename Sauvage's vertebra Saurornithoides, (2) knew the latter name was preoccupied because Henry Osborn had already tied it to something else entirely in 1924, and (3) went ahead and renamed the same remains Caudocoelus sauvagi ("Sauvage's hollow tail") in 1932 to avoid any future confusion. Bless him.

The critter drifted off into obscurity, and there it stayed for thirty odd years until a review by John Ostrom in 1969 which revealed the priority of Nopcsa's name, and the fact that he had neglected to attach a species epithet so it wasn't actually valid. George Olshevsky combined the two names in 1978, thus coining Teinurosaurus sauvagei, but it hardly seems worth it since the fossil in question was blown to kingdom come by German bombing raids during WWII.
Teinurosaurus is derived from the Greek "teino" (stretch), "oura" (tail) and "sauros" (lizard). The species epithet, sauvagei, honors French paleontologist Henri-Émile Sauvage.
