That solves the mystery of the "Cleveland Lloyd ankylosaur (https://twitter.com/Paleojim/status/1252261474275213313).Davidowhttps://www.blogger.com/profile/06099864739987549261noreply@blogger.comtag:blogger.com,1999:blog-6574000839639433662.post-70484015235052026182020-04-19T16:14:20.161-05:002020-04-19T16:14:20.161-05:00"The putative Kallamedu Formation stegosaur h..."The putative Kallamedu Formation stegosaur has been re-identified as a titanosaur..."<br /><br />After living with titanosaurs for two years, that just seems inevitable!Justin Tweethttps://www.blogger.com/profile/01792470288586894872noreply@blogger.comtag:blogger.com,1999:blog-6574000839639433662.post-50879920122206613732020-04-19T15:30:25.904-05:002020-04-19T15:30:25.904-05:00The putative Kallamedu Formation stegosaur has bee...The putative Kallamedu Formation stegosaur has been re-identified as a titanosaur by Galton and Ayyasami (2017), while the putative report of Hypsilophodontidae from Uruguay is probably based on indeterminate iguanodontian teeth reported by von Huene (1934) and described by Soto et al. (2012) as this is the only record of Ornithischia from Uruguay. Meanwhile, the ceratopsian remains reported from Coahuila by Werner Janensch has nothing to do with Coahuilaceratops, as the authors of the Coahuilaceratops description don't mention Janensch (1926). The Lightning Ridge hypsilophodont entry mentioned is clearly Fulgurotherium, as this was the only taxon reported from Lightning Ridge when Glut's 1982 book was published. Finally, the putative hypsilophodont record from Switzerland may be the tooth eventually published by Tatarinov (1985) and assigned to heterodontosaurid, but later placed at Archosauriformes indeterminate by Butler et al. (2006).<br /><br />Butler R.J, Porro L.B, Heckert A.B.
