The first fossils found in the Lameta Formation were discovered between 1917 and 1919. [2]The Lameta Formation was first identified in 1981 by geologists working for the Geological Survey of India (GSI), G. N. Dwivedi and Dhananjay Mahendrakumar Mohabey, after being given limestone structures–later recognised as dinosaur eggs–by workers of the ACC Cement Quarry in the village of Rahioli ...
Indeterminate bird skeleton. Fossil plants from the same area as the McAbee fossil beds (Cache Creek and Kamloops B.C.) were first reported by G.M. Dawson. [8]Palaeontological and geological studies of the McAbee Fossil Beds first commenced in the 1960s and early 1970s by Len Hills of the University of Calgary and his students on the fossil palynology (spores and pollen) and leaf fossils, [9 ...
Cope's neo-Latin type species name sideropelicus (from Greek sidēros "iron" + Greek pēlos "clay" + -ikos) "of iron clay" alluded to the Wichita beds in Texas, where the fossil was found. Diadectes fossil remains are known from a number of locations across North America, especially the Texas Red Beds ( Wichita and Clear Fork).
Scansoriopterygidae (meaning "climbing wings") is an extinct family of climbing and gliding maniraptoran dinosaurs.Scansoriopterygids are known from five well-preserved fossils, representing four species, unearthed in the Tiaojishan Formation fossil beds (dating to the mid-late Jurassic Period) of Liaoning and Hebei, China.
The Beneckeia beds date back to the Anisian stage of the Middle Triassic, and the Ceratites beds date back to the end of the Anisian and beginning of the Ladinian stage. [ 1 ] Swedish paleontologist F. Brotzen described placodont armor from Makhtesh Ramon in 1957, naming the species Psephosaurus mosis and Psephosaurus picardi from the Beneckeia ...
Owen first recognized the genus in 1849. [9] This first fossil was two amphicoelous vertebrae, vertebrae with two concave sides of the centrum, discovered by Professor Henry Roger. It was found in the greensand beds in New Jersey. [9] The different greensand beds of New Jersey represent a complete record from the Cretaceous to the Paleocene.
The trunk of Archaeopteris macilenta has been found to have a diameter of 1 m and an estimated height of 30 m, which may have attributed to its early success. Root systems rarely went deeper than 10 to 20 cm but depths in excess of 1 m have been reported for this tree.
Leidy compared Bathygnathus with Thecodontosaurus from the Triassic red beds of the United Kingdom, one of the first dinosaurs to have been described scientifically. Dawson inferred that Bathygnathus was a fast-moving carnivore, reasoning that its deep skull was similar to the short skulls of fast-moving snakes and unlike the long skulls of ...
