TL;DR: An initial quantitative framework for morphological evolution in Saurichthys is provided by focusing on a single bone, the opercle and exploring patterns of interspecific variability in shape using outline‐based geometric morphometrics and linear measurements.

TL;DR: The new neopterygian genus Ticinolepis, including two new species T. longaeva and T. crassidens, is described from Middle Triassic carbonate platform deposits of the Monte San Giorgio and shows interesting patterns of intraspecific variation including ontogenetic changes and morphological variation over time.

TL;DR: The phylogenetic relationships obtained for the Ionoscopiformes do not show a clear palaeobiogeographic pattern, but give important new insights into the origin, divergence date and early history of this clade.

TL;DR: López-Arbarello et al. as mentioned in this paper established Eosemionotus as the oldest Macrosemiidae within the order Semionotiformes (Ginglymodi), including differential diagnoses for the five species, which differ in body proportions, relative position of the fins, the morphology of several skull bones, and some meristic characters (e.g., number of premaxillary teeth, and branchiostegal rays).

TL;DR: New data on the reproductive biology of these species is presented, giving unprecedented insights into their life‐history, including Ossified squamation and gradual allometric growth suggests that neonates did not undergo metamorphosis and were relatively precocial.
