The Atlantic Plain is generally gently dipping undeformed Mesozoic and Cenozoic sediments, with the sedimentary wedge thickening toward the sea, reaching a maximum thickness of about 3 kilometers (10,000 ft) in the vicinity of Cape Hatteras, North Carolina.
The Mesozoic Sclerorhynchoidea are basal or incertae sedis; they show features of the Rajiformes but have snouts resembling those of sawfishes.
The group contained many families and species during the Mesozoic, but today, only a few species survive.
But given its deep sea habitat, Chondrocladia may well have been around for much longer – perhaps since the Mesozoic, as characteristic spicules (termed "microcricorhabds" or "trochirhabds"), almost identical to those of some living Chondrocladia, are known from Early Jurassic rocks almost 200 million years old.
All other orders of this subclass, which were even more primitive than the living forms, became extinct during the Mesozoic.

These two lineages must have separated during the Mesozoic already, as Madagascar and the Indian Plate had separated by the end of the Cretaceous.
Monger concentrated his research on field studies and detailed geological mapping of upper Paleozoic and lower Mesozoic volcanic and sedimentary layers.
There are many interesting geological features: Hronov-Porici fault, old mines and exposure of Permian-Mesozoic rocks.
The mountains in the park are erosional remnants of resistant igneous rocks that remained after an ancient Mesozoic peneplain surface was uplifted in the Cenozoic to form a plateau, and subsequently dissected via millions of years of erosion by wind, water and glacial ice.
If so, its ancestors must have separated from those of all other living cichlids in the Mesozoic.
However, the great majority of species died out during the Mesozoic, as the more advanced euechinoid sea urchins became common.
Pteridosperms declined during the Mesozoic Era and had mostly disappeared by the end of the Cretaceous Period, though some pteridosperm-like plants seem to have survived into Eocene times, fossilized in Tasmania.
The name was inadvertently used again in 1998 for a fossil species of Mesozoic bird, Rahona ostromi, by Catherine Forster and colleagues.
The essential features of recent groupings seem to have been established during the Mesozoic or early Tertiary.
Boundaries between La Puisaye land and are very clear: they are located where the upper layers of the Jurassic – Mesozoic sink in that the Infra-Cretaceous (Puisaye).
On the advice of the prominent Utrecht natural historian Pieter Harting, he applied a numerical system in which the fossils were divided into Periods (Paleozoic, Mesozoic and Caenozoic) and sorted from 'high' to 'low'.
His research is focused on the systematics and morphometrics of late Mesozoic and Cenozoic bryozoans found in deposits located in the Caribbean, especially the Dominican Republic, Panama, Costa Rica, and Venezuela, and the Gulf coast of the United States, particularly Florida, Alabama, and Mississippi.
The first focuses on the struggling team in the Mesozoic's Maastrichtian Age, some 65 millions years ago.
The boys go back in time to the Cretaceous period of the Mesozoic era and get a Quetzalcoatlus (Harold calls it "Crackers", but George states there's no time to call it a name).
Gwawinapterus is a genus of Mesozoic animal known from a single fossil specimen, representing the single species Gwawinapterus beardi, from the late Cretaceous period of British Columbia, Canada.
He carried out a lot of the early earliest mapping of the Western Highlands and Islands of Scotland, including the Lewisian of Coll and Tiree, the Mesozoic sediments and Tertiary lavas of Morvern and Ardnamurchan, and the Moine Schists of Ardnamurchan, Sunart and South Morar.
Khoratosuchus is the youngest and most advanced Mesozoic crocodyliform yet known from Thailand.
During this time the area was below the Antarctic Circle, and temperatures were relatively cool for the Mesozoic.
The Mesozoic Marine Revolution (MMR) is a term used to describe the rapid adaption to shell-crushing (durophagous) and boring predation in benthic organisms throughout the Mesozoic era, first coined by Geerat J. Vermeij (who based his work on Steven M. Stanley’s).
A wide Mesozoic rift zone, the Basin spans 160,000 square kilometres and has been studied and explored by the oil & gas companies ExxonMobil, Chevron, Imperial Oil, and Shell Canada.
Thomas Maxwell Harris (1903–1983), Mesozoic plants of Jameson Land (Greenland) and Yorkshire.
Taken together, these fossils place the origin of the Papilionoidea in the latest Mesozoic or early Paleogene, while the extant families emerged approximately the early Eocene onwards.
The corals which build reefs today, the Scleractinia, arose after the Permian–Triassic extinction event that wiped out the earlier rugose corals (as well as many other groups), and became increasingly important reef builders throughout the Mesozoic Era.
The large pliosaurs, like the Jurassic Rhomaleosaurus, Liopleurodon and Pliosaurus, and the Cretaceous Kronosaurus and Brachauchenius, were the superpredators of the Mesozoic seas, around 7 to 12 meters in length, and filled a similar ecological role to that of killer whales today.
In addition, thick sequences (accumulations) of Mesozoic-age sedimentary rocks, mostly marine shales and sandstone of Jurassic and Cretaceous age, are locally preserved along the western side of the Peninsular Ranges and throughout the western Transverse Ranges in parts of the Santa Monica Mountains and mountainous Los Padres National Forest region north of Santa Barbara, California.
In association with the names of geologists grouped in the area, it was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Leonard Frank Spath (1882–1957), a British paleontologist and stratigrapher whose study of ammonites made possible the correlation of Mesozoic rocks.
His main areas of study are late Paleozoic, Mesozoic and early Cenozoic vertebrate fossils, stratigraphy, and continental deposits, particularly in the American Southwest.
Stephen Kenneth Donovan FLS (born 3 June 1954) is a British paleaontogolist, who is at Palaeozoic and Mesozoic Macroinvertebrates, Nederlands Centrum voor Biodiversiteit - Naturalis (formerly Nationaal Natuurhistorisch Museum.
Located on upper and middle Shiwaliks, consisting mainly of soft sandstone and clay rocks, the park at present has six sets of life-size models, of Stegodon Ganesha, Sivatherium, Hexaprotodon sivalensis, Colossochelys atlas, Paramachairodus and Crocodilia, Mesozoic animals which once thrived in the region.
Turgai Sea or Turgai Strait, a body of salt water of the Mesozoic and Cenozoic Eras
