It is inevitable that some important specimens will become lost or
damaged over time, conservation is therefore of vital importance. The
Paluxy River dinosaur tracksite is among the most famous in the world.
In 1940, Roland T. Bird described and excavated a portion of the site
containing associated theropod and sauropod trackways. This excavated
trackway was split up and housed in different institutions, and during
the process a portion was lost or destroyed. We applied
photogrammetric techniques to photographs taken by Bird over 70 years
ago, before the trackway was removed, to digitally reconstruct the
site as it was prior to excavation. The 3D digital model offers the
opportunity to corroborate maps drawn by R.T. Bird when the tracksite
was first described. More broadly, this work demonstrates the exciting
potential for digitally recreating palaeontological, geological, or
archaeological specimens that have been lost to science, but for which
photographic documentation exists.
