dinosauria उदाहरण वाक्य
उदाहरण वाक्य
- Together with " Megalosaurus " and " Hylaeosaurus ", it was one of the three genera originally used to define Dinosauria.
- Dinosauria was a massive, diverse clade which existed for hundreds of millions of years ( and still does, in the form of birds ).
- The genus is commonly misspelled " Aepysaurus "; both editions of " The Dinosauria " and a major review use this misspelling.
- However, this synonymy was rejected in the 2004 edition of the " Dinosauria ", with " Stephanosaurus " being tabulated as dubious.
- A year later, when Owen coined the name Dinosauria, he did not include " Cetiosaurus " and " Cardiodon " in that group.
- Towards the end of the twentieth century, the so-called Dinosaur Renaissance took place in which a vast increase in scientific attention was given to the Dinosauria.
- As such, the Dinosauria was no longer seen as a scientific grouping, and " dinosaur " was reduced to being a popular term, without scientific meaning.
- Michael Benton classifies all dinosaurs within the Series Amniota, Class Sauropsida, Subclass Diapsida, Infraclass Archosauromorpha, Division Archosauria, Subdivision Avemetatarsalia, Infradivision Ornithodira, and Superorder Dinosauria.
- However, some controversy remains over whether Megalosauridae should be considered its own distinct group, and dinosaurs in this family remain some of the most problematic taxa in all Dinosauria.
- The raising of the Dinosauria to class rank found less support, perhaps largely due to increasing use of phylogenetic taxonomy among vertebrate palaeontologists, in which ranks are entirely abandoned.
