Upper Cretaceous echinoids from James Ross Basin, Antarctica
New palaeontological collections made from Upper Cretaceous strata exposed within the James RossBasin, Antarctica, include ten echinoid species. Five species are described for the first time from Antarctica, while four others, previously published by Lambert in 1910, are revised according to the new...
