Tetrapod ichnology in Italy. The state of the art. Guest editorial
Full text linkThis year, 2020, marks the 150thanniversary of the seminal work by Giulio Curioni (1870), representing the first published scientific contribution on tetrapod footprints from Italy. We took this opportunity to discuss the current state of the art on tetrapod ichnology in our country, with a jubilee issue, titled "Tetrapod ichnology in Italy: the state of the art". The issue involves the scholars who first pioneered this discipline in Italy in the seventies of the last century, along with all the authors who have worked on the topic in recent decades, and younger generations who have just started to enthusiastically contribute to vertebrate ichnology. After briefly introducing the idea at the base of the Special Issue, as well as some aspects of the discipline and the current methodologies involved in ichnological studies, we present each of the contributions to serve the Italian ichnological heritage
A review of the concepts of ‘axony’ and their bearing on tetrapod ichnology
No full textTwo meanings of the term axony are found in the ichnological literature. Multiple meanings may prove to be a double-edge sword, complicating scientific communication. In vertebrate ichnology the first meaning of axony relies on aspects of locomotion related to the body weight support and propulsive thrust. A second one concerns axony as a purely geometric and dimensional descriptor. These approaches are based on a static view of the impression process, implying the loss of much important information. Here we report an analysis of shallowly impressed footprints referred to the ichnotaxa Ichniotherium sphaerodactylum and Dimetropus osageorum. The analysis was carried out by considering the track registration as a dynamic process and attempting to identify and describe axony conditions during movements. Variations in the axony conditions can be understood in the light of the producer’s foot anatomy and the reciprocal relations between foot bone elements. The concept of axony can be a useful tool in ichnological practice only when it is related to the complex dynamic of locomotion and the resulting track registration. It can help in restoring the interconnections between track and trackmaker, re-establishing the biological significance of tetrapod footprints

The paleontological collection of Egidio Feruglio at MUST
No full textMany fossil specimens whose collection is attributable to Egidio Feruglio were found in the repositories of the Paleontology Museum in the Department of Earth Sciences of ‘Sapienza’ University of Rome, soon became MUST. The material can be traced back to the activity which Feruglio did in Argentina during his two stays between the twenties and forties of the twentieth century. Different available information about this material mainly deriving from tags, label and hand written notes combined with specimens, were organized and are here provided as subsidiary to future museum’s activities
