Chirotherium barthii Kaup 1835 from the Triassic of the Isle of Arran, Scotland

Abstract

Synopsis The mould of a track from SE Arran, and several in situ trackways and individual tracks, as well as a partial trackway on a loose block of Triassic sandstone, from western Arran, represent the first verifiable fossil tracks of Chirotherium from the Triassic of Scotland and support a Scythian (Lower Triassic) age for the base of the Auchenhew Beds. The grouping of the I-IV toes with toe V behind and lateral to the group is characteristic of Chirotherium-like tracks. A comparison with European and American Triassic trackways suggests that the tracks belong to the species Chirotherium barthii Kaup, 1835, first described from Hildburghausen, Germany.

Dinosaur Tracks from the Kilmaluag Formation (Bathonian, Middle Jurassic) of Score Bay, Isle of Skye, Scotland, UK

“…A silicone rubber mould of the best surface was made using the room temperature vulcanising T28 silicone rubber with T6 catalyst, TW catalyst booster, DP 100 release agent, and heavy chopped strand-mat glass fibre from Alec Tiranti Ltd. following the method described by Clark et al (2002). A fibreglass and polyurethane resin cast was made by The Quickening (Glasgow), from the mould and placed with the collections of the Hunterian Museum, University of Glasgow (GLAHM 114912).…”

“…described by Clark et al 2002) and perhaps, in the future, one or two tracks will be removed as a permanent record. A fibreglass cast of these tracks has been made and deposited in the collections of the Hunterian Museum, Glasgow (GLAHM114806).…”

“…[36,92,98,99], England and Scotland e.g. [12,30,42,100], and Poland [33,38,101]. They are also known from North America [22,102], The 'oldest tridactyl tracks from Poland' [103] are nothing else than badly and incompletely printed preserved chirotherid tracks in redbed sand facies.…”
