Though fossils revealing ichthyosaur behavior remain rare, one ichthyosaur fossil is known to have sustained bites to the snout region. Discovered in Australia, and analyzed by Benjamin Kear et alii in 2011, measurements of the wounds reveal that the bite marks were inflicted by another ichthyosaur, likely of the same species, a probable case ...
Ichthyosaurus was the first complete fossil to be discovered in the early 19th century by Mary Anning in England; [9] the holotype of I. communis, no coll. number given, [10] was a fairly complete specimen discovered by Mary and Joseph Anning around 1814 in Lyme Regis [11] but was reported as lost by McGowan (1974) in his review of the ...
The ichthyosaur’s jawbone, or surangular, was a long, curved bone at the top of the lower jaw just behind the teeth, and it measured more than 6.5 feet (2 meters) long.
Ophthalmosaurus (Greek ὀφθάλμος ophthalmos 'eye' and σαῦρος sauros 'lizard') is a genus of ichthyosaur known from the Middle-Late Jurassic. Possible remains from the earliest Cretaceous, around 145 million years ago, are also known. It was a relatively medium-sized ichthyosaur, measuring 4 m (13 ft) long and weighing 940 kg ...
Argovisaurus (meaning "Aargau lizard") is an extinct genus of ophthalmosaurian ichthyosaur from the Middle Jurassic Hauptrogenstein Formation of Switzerland. The genus contains a single species, A. martafernandezi, known from a partial skeleton. Argovisaurus was a large ichthyosaur compared to its relatives.
Arthropterygius appears to have been a relatively large ichthyosaur, with all species measuring between 3–5 m (9.8–16.4 ft) long. [2] The partially preserved specimen PMO 222.655 has been estimated at 3.8–4.3 metres (12–14 ft) based on comparisons to the contemporary ophthalmosaurid Undorosaurus .
The Ichthyosauriformes are a group of marine reptiles, belonging to the Ichthyosauromorpha, that lived during the Mesozoic.. The stem clade Ichthyosauriformes was in 2014 defined by Ryosuke Motani and colleagues as the group consisting of all ichthyosauromorphs that are more closely related to Ichthyosaurus communis than to Hupehsuchus nanchangensis.
Ophthalmosauridae is an extinct family of thunnosaur ichthyosaurs from the Middle Jurassic to the early Late Cretaceous (Bajocian - Cenomanian) worldwide. [1] Almost all ichthyosaurs from the Middle Jurassic onwards belong to the family, until the extinction of ichthyosaurs in the early Late Cretaceous.
