You're not going to believe your eyes, but a new jaw-dropping paper is available online: de Souza GA, Soares MB, Weinschütz LC, Wilner E, Lopes RT, de Araújo OM, Kellner AW (2021). The first edentulous ceratosaur from South America. Scientific Reports 11 (1): Article number 22281. doi:10.1038/s41598-021-01312-4. The discovery of Berthasaura reveals that not all ceratosaurs from the Late Cretaceous had teeth, because the jaws of Berthasaura lacked teeth. The Asian elaphrosaurine Limusaurus is also toothless, but the Late Cretaceous age of Berthasaura shows that some toothless noasaurids survived into the Late Cretaceous. The recovery of Berthasaura in a basal position within Noasauridae rather in a derived position might be affected by the absence of foot bones in the holotype and the percentage of missing morphological data for Deltadromeus because Berthasaurus is younger than Deltadromeus and other members of Elaphrosaurinae.

The theropod informally called "Saltriosaurus" is finally published after so many years as a nomen nudum: The following link is available here: Dal Sasso C, Maganuco S, Cau A. 2018. The oldest ceratosaurian (Dinosauria: Theropoda), from the Lower Jurassic of Italy, sheds light on the evolution of the three-fingered hand of birds. PeerJ 6:e5976 https://doi.org/10.7717/peerj.5976 Although Scipionyx interested me as the first dinosaur found in Italy (it happens to be named after the Roman general Scipio Africanus, who defeated Hannibal at the Battle of Zama in 202 BCE in Tunisia, ending the Second Punic War), I first heard of the dinosaur now called "Saltriosaurus" while reading the book Scholastic Dinosaurs A To Z back in 2003, but what was informally dubbed "Saltriosaurus" is now called Saltriovenator, and after being initially considered a tetanuran, it is apparently an early ceratosaur.
