The original scale image of Tyrannosaurus from its description.
"Tyrannosaurus and Other Cretaceous Carnivorous Dinosaurs" (1905) a paper by Henry Fairfield Osborn. As the research paper which first described the dinosaur species Tyrannosaurus rex, this paper is of great scientific and historic significance. Tyrannosaurus rex, or T. rex as it is often known as, is one of the most well-known species of dinosaur, and was a large carnivorous dinosaur which lived during the Cretaceous Period. It was one of the last non-avian dinosaur species to become extinct during the Cretaceous-Palaeogene mass extinction event, which took place around 65 million years ago.

In 1902, the American Museum expedition in Montana, led by Mr. Barnum Brown, and accompanied by Professor R. S. Lull, secured considerable portions of the skeleton of one of the great Carnivorous Dinosaurs of Upper Cretaceous or Laramie age. Additional portions of this skeleton (Amer. Mus. No. 973) are now (1905) being taken out. I propose to make this animal the type of the new genus Tyrannosaurus, in reference to its size, which greatly exceeds that of any carnivorous land animal hitherto described.

I also briefly characterize as Dynamosaurus another carnivorous dinosaur, with dermal plates, found by Mr. Brown in 1900. The carnivorous group has hitherto been considered as belonging to the single genus Dryptosaurus, but it is probably little less diversified than its herbivorous contemporaries among the Iguanodontia and Ceratopsia. The generic distinctions which are herein indicated by partially studied remains will probably be intensified by future research. Geological, geographical, and morphological considerations render it a priori probable not only that the above genera as well as Deinodon are distinct from Dryptosaurus but that a fifth Cretaceous genus of somewhat more primitive character, which may be called Albertosaurus, is represented in the British Columbia skulls hitherto described as Dryptosaurus.

19th century

1821

  • De la Beche and Conybeare published a sketchy description of some poorly preserved fossils found in various places and rock layers in southwestern England, for which they coined the genus name Plesiosaurus.~145-146 and 150~ However, the separate origins of these "Plesiosaurus" specimens suggest that they actually came from multiple different kinds of animal. Complicating matters further, these remains were later disposed of so the exact identity of their source the cannot be verified or inferred from the inadequate description in the text. De la Beche and Conybeare also failed to designate a type species for their new genus.~150~


For comments on the geographic source and preservation of the original Plesiosaurus fossils, see 145-146. For comments on their stratigraphic provenance, see 150. For the original publication, see.


1822


1823



1824

1829


1840

  • Owen described the species Plesiosaurus hawkinsi.renamed by Storrs and Taylor 1996.~179~

Owen also described the species Plesiosaurus macromus.~180~

1848


1865

  • Owen described the species Plesiosaurus homalospondylus and P. rostratus. These species are now respectively classified in the genera Microcleidus and Archaeonectrus.~179~
  • Seeley described the species Plesiosaurus cliduchus.~180~

1874


1880


1882


1890

  • Lydekker found Plesiosaurus pirscus, named by Parkinson in 1822, to be a nomen dubium.~150-151~

He also found "Plesiosaurus" cliduchus to be synonymous with P. dolichodeirus.~180~

1895

  • Dames described the new species Plesiosaurus guilelmiiperatoris.[1]

20th century

1909

  • Watson erected the new genus Microcleidus for the species "Plesiosaurus" homalospondylus described by Owen in 1865.~179~

1923

  • Huene described the new species Plesiosaurus brachypterygius.~179~

1940


1964

  • Novozhilov erected the new genus Archaeonectrus for the species "Plesiosaurus" rostratus described by Owen in 1865.~179~

1981


1990

  • Sciau and others contended that Plesiosaurus tournemirensis is a distinctive species in that genus.~146~

1993

  • Storrs observed that the plesiosaurs' use of flippers with extra phalanges as their primary means of locomotion was unique among formerly terrestrial animal groups that adapted to aquatic life.[2]
  • Robert T. Bakker erected the new genus Attenborosaurus for the species "Plesiosaurus" conybeare, described by Sollas in 1881.
