Liliensternus liliensterni

Liliensternus was initially assigned to Halticosaurus as Halticosaurus liliensterni by Friedrich von Huene in 1934. But when Samuel Paul Welles found that the Halticosaurus type specimen—Halticosaurus longotarsus—was dubious on account of its remains being hardly identifiable as the property of a dinosaur, von Huene's critter was in need of a new name. Welles coined Liliensternus in 1984 for Dr. Hugo Rühle von Lilienstern,[•] following the lead of von Huene, who named the epithet after Lilienstern too. But was Liliensternus liliensterni so good they named it twice? Well, no, because despite being the best-represented Triassic theropod from the whole of Europe "the best" isn't that good.
"Liliensternus airelensis"
Giles Cuny and Peter Galton named a second species of Liliensternus - Liliensternus airelensis - in 1993 based on remains from the Moon-Airel Formation of Normandy that C. Larsonneur and Albert-Félix de Lapparent had assigned to Halticoaurus sp. It was renamed Lophostropheus airelensis by Cuny and Martin Ezcurra in 2007.
Etymology
Liliensternus is named in honor of Hugo Ruhle von Lilienstern, full-time doctor and amateur paleontologist from Bedheim, Germany. The species epithet was named for von Lilienstern too, as a thank you for opening a paleontological museum in his castle on 1st July 1934. The Liliensternus fossils remained there until 1969 when they were transferred to the Humboldt Museum in Berlin.
Discovery
The first remains of Liliensternus were discovered in the Trossingen Formation of Großen Gleichberg, Römhild, Thuringia, central Germany by Hugo Rühle von Lilienstern in 1922 and 1923. In keeping with the bad habits of early paleontologists, Lilienternus liliensterni was not assigned a holotype. Welles named the "larger" of two specimens (HMN BM.R 2175) as a syntype in 1984 but it's almost impossible to separate the pair by size (there may even be more than two of them) so all of its remains were bundled together by Rauhaut and Hungerbuühler in 1998.
