When a type locality is listed as the site for a formation with many good outcrops, the site is flagged with a note ([Note 2]). When a particular site of note is listed for an extensive fossil-bearing formation, but that site is somehow atypical, it is also flagged with a note ([Note 3]).
[1] [2] It is a Geological Conservation Review site. [3] [4] These eroding cliffs expose a mid-Cretaceous sequence from the Albian to the succeeding Cenomanian around 100 million years ago, with exceptionally rich Albian ammonite fossils. Biological interest is provided by a colony of breeding fulmars on the cliff face. [5] There is public ...
These ammonites lived in the Jurassic from Sinemurian to Toarcian [2] (age range: 196.5 to 182.0 million years ago). Fossils of this genus can be found in Argentina, Austria, Canada, Chile, China, France, Germany, Hungary, Italy, Morocco, Portugal, Slovakia, Spain, Tunisia, Turkey and United States.
This list of ammonites is a comprehensive listing of genera that are included in the subclass †Ammonoidea, excluding purely vernacular terms. The list includes genera that are commonly accepted as valid, as well as those that may be invalid or doubtful ( nomina dubia ), or were not formally published ( nomina nuda ), as well as junior ...
Douvilleiceras is a genus of ammonites from the Middle to Late Cretaceous. Its fossils have been found worldwide, in Africa , Asia , Europe , and North and South America . Description
Parapuzosia seppenradensis is the largest known species of ammonite. [1] It lived during the Lower Campanian Epoch of the Late Cretaceous period, in marine environments in what is now Westphalia, Germany. A specimen, found in Seppenrade near Lüdinghausen, Germany in 1895 measures 1.8 m (5.9 ft) in diameter, although the living chamber is ...
The site is now known as the Truckie Beds. In 1930 M. R. Harrington was searching for Pueblo Indian pottery when he serendipitously discovered the skull of a ground sloth in Gypsum Cave in southern Nevada. Harrington later returned to the site and uncovered more of the sloth's bones. [5]
Arietites is a genus of massive, giant evolute, psiloceratacean ammonites in the family Arietitidae in which whorls are subquadrate and transversely ribbed and low keels in triplicate, separated by a pair of longitudinal grooves, run along the venter. Fossils are known world wide from the lower Sinemurian stage of the Lower Jurassic.
