The “oldest” fossil reptile found within the Italian Alps from the early Permian age has been deemed a forgery by researchers, based on a paper printed within the journal Palaeontology. The reptile, referred to as Tridentinosaurus antiquus was found within the Italian Alps in 1931 and was initially regarded as a chunk of the puzzle of early reptile evolution.
The small, lizard-like reptile featured a protracted neck, a slender physique and pentadactyl limbs. It was first described in 1959 as an “exceptionally preserved fossil exhibiting a dark-coloured physique define related to an articulated skeleton contrasting with the encompassing pale-pink colored tuffaceous sandstone,” the researchers wrote of their paper.
The picture of the lizard was extremely lifelike and certainly had an overview of a lizard. Nevertheless, Italian researchers Valentina Rossi, Massimo Bernardi, Mariagabriella Fornasiero, Fabrizio Nestola, Richard Unitt, Stefano Castelli, Evelyn Kustatscher have referred to as the fossil a forgery.

D, enlargement of the shoulder area, outlined on A. E, enlargement of the pelvic girdle area, outlined on A. Scale bars characterize: 20 mm (A); 5 mm (D); 3 mm (E)
With the help of ultraviolet gentle, 3D floor modeling, the Italians reanalyzed T. antiquus with “ultraviolet gentle, 3D floor modeling, scanning electron microscopy coupled with power dispersive spectroscopy (SEM-EDS), micro x-ray diffraction (μ-XRD), Raman and attenuated whole reflectance Fourier remodeled infrared (ATR-FTIR) spectroscopy,” and located that T. antiquus was not because it appeared, as an vital fossil lizard cited in numerous scientific journals during the last 60+ years as a key piece of the reptile evolution puzzle. The scientists say that with assistance from a manufactured pigment, T. antiquus is a pretend.

The researchers say that the T. antiquus specimen doesn’t retain the essential traits which can be widespread in a “fossil vertebrate with organically preserved tender tissues,” similar to compression fossils. In addition they word that natural materials doesn’t usually fluoresce underneath UV gentle, but the realm wherein the so-called tender tissues is situated fluoresces underneath UV gentle, suggesting that the fabric is of artificial origin, similar to a lacquer, varnish, glue and sure synthetic pigments, which fluoresce underneath UV gentle. The researchers say that certainly one of extra layers of an unknown coating has been utilized on the physique define, osteoderms and bones.
