Popis:	The Hampshire Basin in southern England is the only sequence virtually spanning the Eocene-Oligocene boundary in western Europe. It has provided an opportunity to observe changes in populations across the Grande Coupure event, as an overturn in the squamate assemblage of continental Europe has also been noted. Five Tertiary formations have yielded lizard material: Creechbarrow Limestone, Barton Clay, Headon Hill, Bembridge Limestone and Bouldnor Formation. These formations span the period from the late Middle Eocene to the earliest Oligocene. Localities in the Hampshire Basin represent a depositional environment with an increasing tendency towards lacustrine and riparian influences in later horizons. The anguimorph fauna includes one new anguine, Headonhillia parva gen. et sp. nov., diagnosed by: (1) small size, (2) large parietal area levis, and (3) short parietal crista postfovealis. Another anguine, Ophisaurus sp., is identified on the basis of the morphology of the parietal. Three further morphotypes ...
