Out-of-date YouTube video on turtle origins

Phylogenetic analysis that includes all competing taxa recovers two unrelated origins for the diapsid skull architecture. Turtles are recovered in neither of these. Genomic research too often recovers false positives in deep time studies and does not inlcude fossils So forget genes. They turn good paleontologists into bad paleontologists.
That’s why it is untenable that turtles nest with crocs + dinosaurs @4:18
@4:46 Eunotosaurus is related to Datheosaurus and Casea, not turtles. This is an example of convergence and taxon exclusion = cherry-picking which taxa are tested in analysis.
@8:11 Pappochelys is a placodont, a marine clade that produced turtle-like taxa by convergence, as is widely known and accepted. This is also an example of convergence and taxon exclusion = cherry-picking which taxa are tested in analysis.
Phylogenetic analysis that includes all competing taxa nests softshell turtles with the small horned pareiasaur, Sclerosaurus, followed by Sphodrosaurus, Odontochelys, Ocepechelon, then extant Trionyx and Perochelys.
Meanwhile the hardshell turtles had their own genesis with another horned pareiasaur, Bunostegos, followed by smaller Arganaceras + Yinshanosaurus, then an even smaller pareiasaur with longer horns, Elgina. This taxon nests basal to turnes with large horns, Ninjemys and Niolamia both lack a shell. Horned Meiolania, is the most primitive hardshell turtle with a carapace and plastron. Triassic Proganochelys loses the horns, but retains a longish armored tail.
Cladogram at the large reptile tree (LRT) online. The LRT includes 2340 taxa in order to minimize the possibility of taxon exclusion that hobbles prior turtle studies.
Look for ‘the dual origin of turtles’ online at ResearchGate for more details.
