Triassic archosaur tracks found in the Alps in Switzerland:

New vertebrate trackways from the autochthonous cover of the Aiguilles
Rouges Massif and reevaluation of the dinosaur record in the Valais,
SW Switzerland.

A new tracksite located in the Mesozoic autochthonous series covering
the Aiguilles Rouges Massif, circa 7 km to the NNE of the tracksite of
the Vieux Emosson, is briefly described. The trampled bed is most
likely coeval with the outcrop in the Vieux Emosson area. Two poorly
preserved quadrupedal trackways, almost parallel, measure 9.8 and 8 m
in length, respectively. They are referred to the Chirotheriidae ABEL,
1835 form-family. A short and well-preserved quadrupedal trackway,
composed of two manus-pes couples, is assigned to Chirotherium cf.
barthii KAUP, 1835. A reinterpretation of the Vieux Emosson ichnotaxa
reveals that most tracks, if not all, belong to indeterminate
chirotheriid and that no clear evidence of dinosaur footprints is
observed. The trampled bed of the cover of the Aiguilles Rouges Massif
probably forms a megatracksite, which is Early or Middle Triassic in
age.
