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 ...
Many of these also have much or all of the original shell, as well as the complete body chamber, still intact. Many Pierre Shale ammonites, and indeed many ammonites throughout earth history, are found inside concretions. Other fossils, such as many found in Madagascar and Alberta, Canada display iridescence.
Parapuzosia is an extinct genus of desmoceratid ammonites from the Cenomanian to the Campanian of Africa, Europe, and North America. [2] They are typically very large ammonites, reaching diameters of 60 cm (2.0 ft) or more, with the largest species measuring around 2 m (6.6 ft). [3]
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
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 ...
The fossils include unique species of fish that had never been found in the area before. The discovery is reshaping views on California geology with the possibility of extinct islands.
The largest ammonite ever found, a specimen of Parapuzosia seppenradensis measuring 1.742 m (5.72 ft) in diameter. The fossil pictured is the original held at the Westfälisches Museum für Naturkunde in Münster, but many casts exist.
A massive jawbone found by a father-daughter fossil-collecting duo on a beach in Somerset along the English coast belonged to a newfound species that’s likely the largest known marine reptile to ...
