Exempel på hur man kan använda ACRODONT i en mening

• Squamata: Within squamate reptiles, acrodont tooth implantation is best known in Acrodonta and some species of amphisbaenians, though some snakes are also referred to as being acrodont.
• Thecodont reptiles and theropod dinosaur fossils have an interdental plate, whereas acrodont reptiles such as Sphenodontia do not.
• Its pleuroacrodont dentition is similar to Gephyrosaurus (a basal rhynchocephalian) and Gueragama (a basal acrodontan squamate), which are each early members of major lepidosaur lineages with acrodont dentition.
• Thecodont dentition is a morphological arrangement in which the base of the tooth is completely enclosed in a deep socket of bone, as seen in crocodilians, dinosaurs and mammals, and opposed to acrodont and pleurodont dentition seen in squamate reptiles.
• Some specimens preserve hatchling teeth between the acrodont and pleurodont teeth, which are conical and laterally compressed.
• Some traits, such as the acrodont or pleurodont tooth implantation and spoon-shaped sclerotic bones are unprecedented for dinosaurs as a whole, and instead, are common among modern lizards.
• It is a small sphenodontian with a skull roughly 20 mm long, and represents a unique mosaic of characteristics shared by both early diverging sphenodontians (such as a broad parietal table, multiple tooth rows on the palate, and an elongated premaxillary process) and eusphenodontian characters (full acrodont dentition, high coronoid process and anterior successional teeth, including the earliest known caniniforms in a lepidosaur).
• The jaws have a combination of slightly backward curving (recurved) column-like pleurodont front teeth attached to the inner side of the jaw along with larger posterior triangular acrodont teeth attached to the apex of the jaw bone, similar to other primitive rhynchocephalians like Diphydontosaurus.
