Ammonites in the permanent collection of The Children's Museum of Indianapolis. At least 57 species of ammonites, which were widespread and belonged to six superfamilies, were extant during the last 500,000 years of the Cretaceous, indicating that ammonites remained highly diverse until the very end of their existence.
Ammon (Ammonite: 𐤏𐤌𐤍 ʻAmān; Hebrew: עַמּוֹן ʻAmmōn; Arabic: عمّون, romanized: ʻAmmūn) was an ancient Semitic-speaking kingdom occupying the east of the Jordan River, between the torrent valleys of Arnon and Jabbok, in present-day Jordan.
Although almost all evidence indicated that ammonites did not survive past the K–Pg boundary, there is some scattered evidence that some ammonites lived for a short period of time during the Paleocene epoch, although none survived the Danian (66-61 Ma); [1] they were likely extinct within 500,000 years of the K-Pg extinction event, which ...
Of the few genera of ammonites which are thought to have survived the K-Pg extinction event into the Danian period (65-61 Myr) of the Paleogene, Hoploscaphites is the most widely and reliably recorded, with finds in Denmark, the Netherlands and the United States, and a possible record in Turkmenistan.
Ammonitida or "True ammonites" are an order of ammonoid cephalopods that lived from the Jurassic through Paleocene time periods, commonly with intricate ammonitic sutures. Ammonitida is divided into four suborders, the Phylloceratina , Lytoceratina , Ancyloceratina , and Ammonitina .
The Dalle à ammonites (or Dalle aux ammonites) at Digne-les-Bains (Alpes-de-Haute-Provence) is a remarkable natural site consisting of a rock strata bearing a large number of fossilized ammonites. This site is located approximately 1.5 kilometres (0.93 mi) south of Digne-les-Bains from Barles road.
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 ...
