The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends (2019, background): “Unserrated teeth are present in the whole dentition of: the noasaurid Limusaurus [Wang et al.'s (2017a) data matrix]; spinosaurines such as Irritator (Sues et al., 2002; Figure 11.3), Angaturama (Kellner and Campos, 1996), and Spinosaurus (Stromer, 1915); the neocoelurosaur Fukuivenator (Azuma et al”
A new megalosaurid theropod dinosaur from the late Middle Jurassic (Callovian) of north-western Germany: Implications for theropod evolution and faunal turnover in the Jurassic (2016, background): “Unlike the situation in Torvosaurus (Britt, 1991), spinosaurids (Charig and Milner, 1997; Sues et al., 2002), and Sciurumimus (Rauhut et al., 2012), but as in most theropods, including Ceratosaurus (Madsen and Welles, 2000), Dubreuillosaurus (Allain, 2002), Afrovenator (Sereno et al., 1994) and…”
The Dentition of Megalosaurid Theropods (2014, background): “…always reaches the cervix, the enamel texture is deeply veined (except in Irritator) and the crowns are subcircular in cross-section and sometimes fluted on one or both lingual and labial surfaces (e.g., Charig and Milner 1997; Sereno et al. 1998; Sues et al. 2002; Hendrickx and Mateus 2014b).”
HETERODONTY IN TYRANNOSAURUS REX: IMPLICATIONS FOR THE TAXONOMIC AND SYSTEMATIC UTILITY OF THEROPOD DENTITIONS (2005, background): “Although the key characters uniting the Spinosaurinae are all related to the dentition (see Sereno et al., 1998; Sues et al., 2002), and such features have been important in studies of toothed birds, for most groups even works that describe the dentigerous bones in detail refer to the teeth…”
The phylogeny of Tetanurae (Dinosauria: Theropoda) (2012, background): “Spinosaurid theropod with nasals exhibiting prominent median bony crest that terminates posteriorly in knob-like, somewhat dorsoventrally flattened projection (Sues et al. 2002).”
A description of Megalosaurus bucklandii (Dinosauria: Theropoda) from the Bathonian of the UK and the relationships of Middle Jurassic theropods (2010, background): “The presence of a maxillary ‘fenestra’ with the form of a subcircular fossa (character 15.1; transformed to 2 in Irritator) is a synapomorphy of Megalosauroidea under DELTRAN.”
