Stump P-47 model

Excavation and in situ presentation of FLFO stumps over the past 130 years have resulted in their continued deterioration including cracking, spalling, and loss that compromises the integrity of these important fossil specimens. Their current condition has been investigated through a general condition survey and an environmental assessment of their immediate context. One stump, P-47, was selected as an ideal specimen for in-depth examination and physico-chemical analysis in order to establish baseline conditions and to explain deterioration mechanisms at large. P-47 exhibits almost every deterioration pattern observed at the park. This specimen is also ideal because it was excavated by dynamite blasting and because it is situated at the centre of an unsheltered excavated depression. A conservation treatment program, and lab tested, focuses on mechanical pinning to address large scale loss and detachment. Source: Objaverse 1.0 / Sketchfab
