Mary Buckland, also known as Mary Morland, contributed to paleontology through fossil collecting and scientific illustration. Her drawings made anatomical details of specimens available for comparison by researchers who could not examine the original fossils directly.

The Geological Society's collections identify her drawings of a Megalosaurus jaw used with William Buckland's 1824 description, and views of a fossil rhinoceros skull published in Georges Cuvier's work. These are specific contributions to the visual evidence of comparative anatomy: orientation, preserved margins and visible structures have to be communicated accurately for a reader to assess a reconstruction. The illustration credit and the authorship of the accompanying paper are distinct historical claims.^[ref]

Megalosaurus is a genus of extinct predatory theropod dinosaurs known from Jurassic remains in England. Fossil jaw and limb material from Stonesfield contributed to its early recognition. William Buckland published a description in 1824, before the later name Dinosauria had been introduced. ^[ref]

The preserved lower jaw illustrates how specific observations constrain reconstruction. Serrated, blade-like teeth support a meat-eating interpretation, while imaging can reveal replacement teeth hidden within the bone. A fossil specimen and a complete life reconstruction contain different amounts of direct evidence: posture, missing anatomy and evolutionary relationships require comparisons beyond the isolated jaw.

William Buckland was a geologist and paleontologist whose 1824 description of Megalosaurus became the first full published account of an animal later recognized as a dinosaur. The work treated large fossil bones from Stonesfield, including a lower jaw now preserved at the Oxford University Museum of Natural History. The surviving specimen connects the historical interpretation directly to an object that can still be re-examined.^[ref]

Mary Buckland, then Mary Morland, contributed the jaw illustration to the Megalosaurus account; careful scientific drawing was part of recording the fossil evidence. William Buckland's later Geology and Mineralogy Considered with Reference to Natural Theology by William Buckland explicitly placed geology and mineralogy within a natural-theological project. These historical commitments should be distinguished from the specimen descriptions and other evidence that later researchers could test.^[ref]
