Diplomoceratidae
Diplomoceratidae is a family of ammonites included in the order Ammonitida. Fossils of species within this genus have been found in the Cretaceous sediments (age range: from 99.7 to 66.043 million years ago). Studies of ''Diplomoceras'' suggest that members of this family could reach lifespans of over 200 years.

Scalarites
''Scalarites'' is a genus of heteromorph ammonites included in the family Diplomoceratidae. These fast-moving nektonic carnivores lived in the Cretaceous period, from 89.3 to 70.6 million years ago).

Leonard Frank Spath
Leonard Frank Spath FRS (20 October 1882 – 2 March 1957) was a British geologist specialising in malacology and ammonitology. Education Spath gained a Bachelor of Science degree in geology at Birkbeck College in 1912 and obtained employment at the British Museum as an assistant curator in the geology department. He undertook two geology field trips, to Tunisia and Newfoundland, around that time which he used as an opportunity to collect fossils. He later gained a Doctor of Science degree from the University of London and was a lecturer in Geology at Birkbeck, University of London. Awards and honours Spath was elected a Fellow of the Royal Society (FRS) in 1940, his certificate of election reads: Spath won the prestigious annual scientific Lyell Medal given by the Geological Society of London The Geological Society of London, known commonly as the Geological Society, is a learned society based in the United Kingdom.

Ammonitida
Ammonitida is 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 Phylloceratina is the ancestral stock, derived from the Ceratitida near the end of the Triassic. The Phylloceratina gave rise to the Lytoceratina near the beginning of the Jurassic which in turn gave rise to the highly specialized Ancyloceratina near the end of the Jurassic. Both the Phylloceratina and Lytoceratina gave rise to various stocks combined in the Ammonitina. These four suborders are further divided into different stocks, comprising various families combined into superfamilies. Some like the Hildoceratoidea and Stephanoceratoidea are restricted to the Jurassic. Others like the Hoplitoidea and Acanthoceratoidea are known only from the Cretaceous. Still others like the Perisphinctoidea are found in both. R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

The Independent
''The Independent'' is a British online newspaper. It was established in 1986 as a national morning printed paper.
