A paleontologist who combined morphological and molecular evidence to investigate the transition from teeth to baleen in cetaceans.^[ref]

A paleontologist who investigated developmental and comparative evidence about digit identity in vertebrate limbs, including the correspondence of digits in bird wings.^[ref]

A paleontologist who used carbon isotope ratio measurements in tooth enamel to reconstruct dietary resources used by Paranthropus boisei.^[ref]

A paleontologist who investigated very old DNA from mammoths, using genome data to test population history and ancestry of extinct lineages.^[ref]

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]

A paleontologist who studied feathered dinosaur fossils, including evidence that large body size did not preclude an extensive covering of feathers.^[ref]

A paleontologist who investigated early mammalian anatomy and relationships, including competing interpretations of the origin of tribosphenic teeth.^[ref]

A paleontologist who investigated the anatomy of early jawless vertebrates, using galeaspid evidence to test hypotheses about the origin of paired appendages.^[ref]
