Samuel H. Beckles (1814–1890) was an English 19th century dinosaur hunter, who collected remains in Sussex and the Isle of Wight. In 1854 he described bird-like trackways that he thought could have been made by dinosaurs, which he later identified as probably those of an Iguanodon in 1862.[1][2] In 1857, following the discovery of a mammal jaw at Durlston Bay, he directed a major excavation that became known as 'Beckles' Pit', removing 16 m of overburden over a 600 square metre area, one of the largest ever scientific excavations. The collection of mammal fossils that resulted is now held at the Natural History Museum.[3] He discovered the small herbivorous dinosaur Echinodon. The only known species Echinodon becklesii and the dinosaur Becklespinax were named in his honour.
