  • I found this… dinosaur footprint

    By Simon J Jackson, on 10 October 2012

    I found this… is a new mini-installation by the entrance to the Museum. In each of the six cabinets one member of our team has selected one object which they have uncovered something new about. Today…

    The dinosaur footprint

    Dinosaur Footprint As I worked my way through documenting numerous specimens in the stores, I was pleased to come upon this specimen, one of three plaster casts of dinosaur footprints from the Isle of Wight Francis Mussett Collection. Having completed a Ph.D. in dinosaur footprint formation, it was a great opportunity for me to apply my expertise to the specimens. Firstly, by comparing the specimen to other footprints in the literature, and ones I have studied, I was able to ascertain that the animal that made this footprint was probably a flesh eating or carnivorous dinosaur — note the three long slender digits pointing forward with pointed terminations. By using a well-known relationship between footprint length and hip height, I was able to ascertain that the dinosaur would have been approximately 1 m high at the hip, and therefore about 3 to 4 m in length. The web-like structure between two of the toe imprints was probably formed from sediment being squeezed between the toes as the foot impacted upon the sediment. Thus the original ‘mould’ of the foot may have been slightly modified by the movement of the sediment, which means our interpretation of the animal’s size and type needs to be treated with some caution.
