Short summary
Using biometric analysis, a new species, Similiscutum giganteum, has been described. Given its distinctive morphology and its stratigraphic range restricted to upper Pliensbachian and Toarcian, the potential stratigraphic use of this new species has to be explored. A method for biometry is also described in detail. This paper proves the value of biometric analysis in taxonomic description.
