Exempel på hur man kan använda COMPSOGNATHIDS i en mening

• Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today.
• Tetanurae (/ˌtɛtəˈnjuːriː/ or "stiff tails") is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, and coelurosaurs (which includes tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans, the latter including living birds).
• In 2024, Andrea Cau published a study on the phylogenetics of compsognathids that recovered Mirischia, along with four other proposed Compsognathids in a polytomy within basal Coelurosauria.
• The paleontologists describe Aniksosaurus as "more derived than some basal coelurosaurians such as compsognathids, Ornitholestes, and coelurids", but less advanced than later coelurosaurs such as Tyrannosaurus and Oviraptor.
• Some authors have proposed that Compsognathidae is not a monophyletic group, and at least some compsognathids represent juvenile specimens of larger tetanuran theropods, such as carnosaurs and tyrannosaurs.
• The specialized teeth resemble those of some maniraptoriform theropods, namely the deinonychosaurs and compsognathids.
• They found that the support for the placement of Haplocheirus within alvarezsaurs and within compsognathids was roughly equivalent to the support values of the trees which placed it in ornithomimosaurs.
• Additionally, he argued that the characters cited are not unique to compsognathids, with fan-shaped neural spines being also seen in ornithomimosaurs and the troodontid Sinovenator, and the robust I-1 phalanx also being seen in alvarezsaurids.
