= “Ornithopsis” leedsi MARTILL & CLARKE, 1994

Locality: Peterborough old gasworks, Cambridgeshire County, England, Southern United Kingdom.

Horizon: Kellaways Formation.

Biostratigraphy:

Age: Callovian Stage, Upper Dogger Epoch, Middle Jurassic.

Material:

Number: Not given: Hip bones.

Note: The rest of the skeleton could still be on site.

Note: Huene, 1927a named Cetiosauriscus leedsi for Ceitosaurus leedsi, but not the type of C. leedsi, but for the referred specimen published by WOODWARD, 1905. His1927a paper was confusing, but his 1927b paper explained it better. Charig, 1980 followed his first paper and renamed the species to stewarti. This is unwarranted because genera can have the same species name and is here emended back to Huene’s original description. The ICZN ruled in favor of CHARIG in 1995 therefore the correct species is stewarti and not leedsi.
