Robert Plot’s discovery in 1677 marks an important milestone in the history of paleontology. Here are more detailed points about his discovery and its significance:
### Background and Discovery
– **Robert Plot**: He was an English naturalist, professor of chemistry at the University of Oxford, and the first curator of the Ashmolean Museum.
– **Discovery Site**: The bone was found in a limestone quarry in Cornwell, Oxfordshire, England.
– **Bone Description**: Plot described the bone in his book “The Natural History of Oxfordshire,” published in 1677. He depicted it as a large thigh bone (femur) and believed it belonged to a giant human or possibly an elephant brought to Britain by the Romans.
### Initial Misinterpretation
– **Giant Human Hypothesis**: At the time, the concept of dinosaurs did not exist, so large bones were often attributed to biblical giants or other large animals.
– **Plot’s Illustrations**: He included illustrations of the bone in his book, which were later used to identify the bone correctly.
### Re-evaluation and Modern Understanding
– **William Buckland**: In the early 19th century, William Buckland, another English geologist and paleontologist, revisited Plot’s findings. Buckland is credited with describing and naming Megalosaurus in 1824, recognizing the bone as part of this dinosaur.
– **Megalosaurus**: This dinosaur is now known to be a large carnivorous theropod that lived during the Middle Jurassic period, approximately 166 million years ago. It was one of the first dinosaurs to be described and named scientifically.
### Significance
– **First Dinosaur Bone**: Plot’s discovery is considered the first recorded instance of a dinosaur bone, even though its true nature wasn’t understood at the time.
– **Advancement in Paleontology**: This discovery laid the groundwork for future paleontological studies, leading to the eventual recognition of dinosaurs as a distinct group of prehistoric animals.
– **Historical Context**: The misinterpretation of the bone highlights the evolving nature of scientific understanding and the gradual development of paleontology as a field.
### Legacy
– **Ashmolean Museum**: Plot’s role as the first curator helped establish one of the world’s first university museums, which still exists today as part of the University of Oxford.
– **Historical Recognition**: The re-evaluation of Plot’s discovery in the 19th century by Buckland and others underscores the importance of revisiting historical scientific findings with new knowledge and techniques.
Plot’s initial discovery, though misinterpreted, ultimately contributed to the foundation of dinosaur paleontology, illustrating the progression of scientific inquiry and understanding over time.
