Velocipes

Velocipes (meaning "quick foot") is a saurischian dinosaur genus from the Late Triassic that may have been a theropod. Its fossils were found in the Norian-age Lissauer Breccia of southern Poland.
Upon discovery, "Velocipes" was thought to have been a coelurosaur, but more recent studies have shown that "Velocipes" was probably a basal theropod or dinosauriform.
History and taxonomy.
The type species, "V. guerichi", was first described by Huene in 1932 as a coelurosaur, based on the proximal portion of a very poorly preserved fibula that was discovered in the Lissauer Breccia of southern Poland by Georg Gürich around 1898. The bone was damaged during the Second World War and was thought to have been destroyed until it was rediscovered in 2012. In 1956, von Huene placed "Velocipes" in the Halticosauridae, which has since become monotypic to only include "Halticosaurus". In 1984, Samuel Paul Welles considered "Velocipes" to be synonymous with "Liliensternus".
A later paper, published in 2000 by Rauhut and Hungerbuhler, claimed that the only specimen of this animal was not well preserved enough to be confidently identified as part of a fibula, and classified the genus as an "indeterminate vertebrate". In 2004, Ronald Tykoski and Timothy Rowe listed "Velocipes" as a possible ceratosaur or coelophysoid. Weishampel "et al." (2004) also listed "Velocipes" as a possible ceratosaur.
However, an SVP abstract reviewing putative dinosauriform remains from the Triassic of southern Poland confirmed the original theropod classification of "Velocipes" by von Huene, which was elaborated in detail in a 2016 paper. The authors considered "Velocipes" to have been a basal theropod or a neotheropod.
Paleoecology.
"Velocipes" would have been contemporaneous with the aetosaur genus "Kocurypelta", an indeterminate species of lungfish and an indeterminate species of stem-turtle from the Proterochersidae family.
