Dinosaur footprint Mount Morgan A1

Dinosaur footprint (A1.2) from the ceiling of the 'fireclay caverns' of Mount Morgan, Queensland, Australia in lake deposits ~195 million years old of Early Jurassic (Sinemurian) and is preserved as a track infill (i.e., an 'outie' rather than an 'innie'). The model was made based on photogrammeteric methods of a plaster replica made from a wax mould by the late 'Ross' Staines in 1954 when working as a geologist at Mount Morgan. Not so much a 'lost' specimen because it was not known to science, this important specimen resolves decades old misconceptions of dinosaur track-maker identity and behaviour from this tracksite that has been permanently closed since 2011.
