“…Despite a dubious report on the occurrence of Pennsylvanian and Permian Hybodontid remains from San Salvador Patlanoaya, Puebla, Mexico (Derycke- Khatir et al, 2005), the present is the first concrete finding of Hybodontid sharks in Mexico. Moreover, the occurrence of Planohybodus in Yosobé is interesting because it complements the broken temporal and geographical distribution previously known of this genus.…”

“…The presence of a slender crown with three keels on its anterior surface and a narrow neck are common features in scales of PaleozoicMesozoic ctenacanthids, but are also common in euselachian chondrichthyans (Reif, 1978;Hansen, 1986;Rieppel et al, 1996;Johns et al, 1997;Derycke-Khatir et al, 2005;Ivanov et al, 2013). The Hydriot denticle compares favorably to the par-agenus Moreyella (Gunnell, 1933;Hansen, 1986), which has been tentatively affiliated with Carboniferous-Permian hybodontiform chondrichthyans (e.g., Derycke-Khatir et al, 2005). The Triassic paragenera Fragilicorona and Labascicorona (Johns et al, 1997) also display very similar, tricuspid distal crowns like the denticle in question, but their systematic affinities beyond the euselachian level have not been discussed (Ivanov et al, 2013).…”

“…2, righthand side): (1) the Magdalena and Chazumba units are Permo-Triassic, whereas part of the Cosoltepec Formation is bracketed between rocks of c. 455 Ma age and the base of unconformably overlying uppermost Devonian sedimentary rocks (Vachard & Flores de Dios 2002;Derycke-Khatir et al 2005;Keppie et al 2006), whereas other parts of the Cosoltepec Formation are younger than c. 410 Ma (post-Silurian: Talavera-Mendoza et al 2005); (2) the Tecomate Formation is of latest Carboniferous-Mid-Permian age (Keppie et al 2004a); (3) the type-Xayacatlán igneous body is of earliest Silurian age and has a continental tholeiitic signature (Dostal et al 2004): other units previously correlated with the Xayacatlan Formation are bracketed between c. 870 Ma and c. 470 Ma (Talavera-Mendoza et al 2005); (4) the tectonothermal events are Devono-Mississippian (eclogite-facies metamorphism: Middleton et al 2005), Permo-Triassic (greenschist-facies metamorphism: Malone et al 2002;Keppie et al 2004aKeppie et al , 2006, and Jurassic (local migmatization and high-temperature-low-pressure metamorphism: Keppie et al 2004b); although Talavera-Mendoza et al (2005) interpreted Ordovician granitoid ages in terms of Taconian-Salinian orogenic events, we suggest that they represent intrusive ages. This has led to reclassifying the Magdalena and Chazumba units as lithodemes of a restricted Petlalcingo Suite .…”
