Samuel Paul Welles
Samuel Paul Welles (November 9, 1907 – August 6, 1997) was an American palaeontologist. Welles was a research associate at the Museum of Palaeontology, University of California, Berkeley. He took part in excavations at the Placerias Quarry in 1930 and the ''Shonisaurus'' discoveries of 1954 and later, in what is now the Berlin-Ichthyosaur State Park. He accumulated an extensive collection of fossils of marine reptiles, amphibians, and fish, as well as describing the dinosaur ''Dilophosaurus'' in 1954 and the elasmosaur Elasmosauridae is an extinct family of plesiosaurs, often called elasmosaurs.

Gloucester, Massachusetts
Gloucester () is a city in Essex County, Massachusetts, in the United States. It sits on Cape Ann and is a part of Massachusetts's North Shore. The population was 29,729 at the 2020 U.S. Census. An important center of the fishing industry and a popular summer destination, Gloucester consists of an urban core on the north side of the harbor and the outlying neighborhoods of Annisquam, Bay View, Lanesville, Folly Cove, Magnolia, Riverdale, East Gloucester, and West Gloucester. History The boundaries of Gloucester originally included the town of Rockport, in an area dubbed "Sandy Bay". The village separated formally from Gloucester on February 27, 1840. In 1873, Gloucester was reincorporated as a city. Contact period Native Americans inhabited what would become northeastern Massachusetts for thousands of years prior to the European colonization of the Americas.

A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Fresnosaurus
''Fresnosaurus'' is an extinct genus of plesiosaur from the Late Cretaceous (Maastrichtian stage) of what is now California. The type species is ''Fresnosaurus drescheri'', first described by Welles in 1943. The generic name ''Fresnosaurus'' honors Fresno County, while the specific name honors Arthur Drescher.S. P. Welles. 1943. Elasmosaurid plesiosaurs with description of new material from California and Colorado. Memoirs of the University of California 13:125-254 ''Fresnosaurus'' was probably at least 9 meters (30 feet) in length. Like all elasmosaurid plesiosaurs, it probably ate small bony fish, belemnites, and ammonites. from the Plesiosauria Translation and Pronunciation Guide See also * |
Elasmosaur
Elasmosauridae is an extinct family of plesiosaurs, often called elasmosaurs. They had the longest necks of the plesiosaurs and existed from the Hauterivian to the Maastrichtian stages of the Cretaceous, and represented one of the two groups of plesiosaurs present at the end of the Cretaceous alongside Polycotylidae. Their diet mainly consisted of crustaceans and molluscs. Description The earliest elasmosaurids were mid-sized, about . In the Late Cretaceous, elasmosaurids grew as large as , such as '' Styxosaurus'', ''Albertonectes'', and '' Thalassomedon''. Their necks were the longest of all the plesiosaurs, with anywhere between 32 and 76 (''Albertonectes'') cervical vertebrae. They weighed up to several tons. Classification Early three-family classification Though Cope had originally recognized ''Elasmosaurus'' as a plesiosaur, in an 1869 paper he placed it, with ''Cimoliasaurus'' and ''Crymocetus'', in a new order of sauropterygian reptiles. He named the group Streptosa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dilophosaurus
''Dilophosaurus'' ( ) is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 193 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942. The most complete specimen became the holotype of a new species in the genus ''Megalosaurus'', named ''M. wetherilli'' by Samuel P. Welles in 1954. Welles found a larger skeleton belonging to the same species in 1964. Realizing it bore crests on its skull, he assigned the species to the new genus ''Dilophosaurus'' in 1970, as ''Dilophosaurus wetherilli''. The genus name means "two-crested lizard", and the species name honors John Wetherill, a Navajo councilor. Further specimens have since been found, including an infant. Footprints have also been attributed to the animal, including resting traces. Another species, ''Dilophosaurus sinensis'' from China, was named in 1993, but was later found to belong to the ge ...

Shonisaurus
''Shonisaurus'' is a very large genus of ichthyosaur. At least 37 incomplete fossil specimens of the marine reptile have been found in the Luning Formation of Nevada, USA. This formation dates to the late Carnian age of the late Triassic period, about 237–227 million years ago. Description left, Size of ''S. popularis'' (green) and '' Shastasaurus sikanniensis'' (red) compared with a human (blue) ''Shonisaurus'' lived during the Carnian stage of the late Triassic period. ''S. popularis'' measured around in length and in body mass. A second species from British Columbia was named ''Shonisaurus sikanniensis'' in 2004. ''S. sikanniensis'' was one of the largest marine reptiles of all time, measuring and weighing . However, phylogenetic studies later showed ''S. sikanniensis'' to be a species of '' Shastasaurus'' rather than ''Shonisaurus''. A new study published in 2013 reasserted the original classification, finding it more closely related to ''Shonisaurus'' than to ''Shasta ...

Placerias
''Placerias'' (meaning 'broad body') is an extinct genus of dicynodonts that lived during the Carnian to the Norian age of the Triassic Period (230–220 million years ago). ''Placerias'' belongs to a group of dicynodonts called Kannemeyeriiformes, which was the last known group of dicynodonts before the taxon became extinct at the end of the Triassic. Description ''Placerias'' was one of the largest herbivores in the Late Triassic, with large skull measuring long and weighing up to with a powerful neck, strong legs, and a barrel-shaped body. There are possible ecological and evolutionary parallels with the modern hippopotamus, spending much of its time during the wet season wallowing in the water, chewing at bankside vegetation. Remaining in the water would also have given ''Placerias'' some protection against land-based predators such as ''Postosuchus''. ''Placerias'' used its beak to slice through thick branches and roots with two short tusks that could be used for defence ...
