Anomphalus jaggerius is an extinct species of Permian sea snail. Fossils have been found in Artinskian era limestone from the Bird Spring Formation in the southern Arrow Canyon Range of the US State of Nevada. The species, which had a shell 6.37 millimetres (0.251 in) wide, was a subtidal epifaunal grazer. [1]
Anguispira russelli was a species of pulmonate land snail in the family Discidae, the disk snails. The species is only known from fossilized specimens. It is named after L.S. Russell, former Director of Zoology at the National Museum of Canada .
†Campanile giganteum is a species of exceptionally large fossil sea snail, marine gastropod mollusks in the family Campanilidae. This species dates from the Eocene epoch. With a shell length of 40 to 90 cm (16 to 35 in) [1] [2] or even more than 120 cm (47 in) [3] this is considered to be one of the largest (lengthwise) species of shelled gastropod that ever lived.
This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell ( sea slugs ) to leave any recognizable traces.
A classic location to find these fossils is Redcar, on the northeast coast of England. There used to be a common folk belief that carrying one of these fossils could prevent rheumatism. The name "devil's toenail" is also used for some fossil species of the genus Exogyra, which is in the same family (Gryphaeidae) as Gryphaea.
One variety of "Turritella agate", that from the Green River Formation in Wyoming, is a fossiliferous rock which does indeed contain numerous high-spired snail shells. However, contrary to the common name, these snails are not in the marine genus Turritella , instead they are freshwater snails in the species Elimia tenera , family Pleuroceridae ...
Known from fossil evidence about 400,000 years old, it is one of many glacial relict species that remain in the Driftless Area, a glacier-eroded plateau that now makes up parts of Iowa, Illinois, Minnesota, and Wisconsin. Much of the area was covered by glaciers about 500,000 years ago, while parts of the Driftless Area were unglaciated.
The genus Vermetus is very ancient: it occurs in the fossil record from the Jurassic to the Quaternary (age range: from 164.7 to 0.0 million years ago). [ 2 ] Species
