Eocene echinoids. Fossil echinoids from the Eocene in Florida are reasonably well-known and diverse. A variety of fossils from the carbonates of the Middle and Upper Eocene have been collected by paleontologists for more than years. Consequently, most of our Eocene taxa and biostratigraphic records are not by: A new Late Eocene cassiduloid (Echinoidea) from Yorke Peninsula, South Australia. Memoirs of Museum Victoria 61(2): – A new species of cassiduloid, from the Muloowurtie Formation on the east coast of Yorke Peninsula, is described and tentatively assigned to the genus Rhynchopygus. R?Cited by: 3. CENOZOIC FOSSIL ECHINOIDS orally, and connected to the interporal par-tition adorally. Interporiferous zones about the width of one pore column. Primary (=marginal of Fell, Fig. ) tuber-cles adjacent to sloping ridges, with one secondary (=internal of Fell, ) tuber-cle per ambulacral plate, offset to second-. t he spectacular fossil gastropods and the teeth of sharks – found at the type locality of the Middle Eocene Bartonian in Christchurch Bay (Hampshire and Dorset) – overshadow the other fauna and flora found there. However, among the ‘Cinderella’ groups are the echinoids (sea urchins). Several kinds, both ‘irregular’ and ‘regular’, can be found, some preserved with superb detail.

Holmes. The roe (egg mass) of some species, notably certain sea urchins, is eaten in some cultures, notably in Japanese sushi; as a result, certain echinoid species are commercially fished. The larval development of echinoids has also been studied extensively, and many discoveries in developmental biology have been made using echinoids.
