The expedition fortuitously was delayed on the return journey for repairs. Crawfurd collected significant fossils, north of Magwe on the left bank of the river, in seven chests. Back in London, William Clift identified a new species of mastodon (more accurately Stegolophodon) from them; Hugh Falconer also worked on the collection. The finds, of fossil bones and wood, were discussed further in a paper by William Buckland, giving details; and they brought Crawfurd the friendship of Roderick Murchison, Foreign Secretary of the Geological Society. There were also collected 18,000 botanical specimens, many of which went to the Calcutta Botanic Garden.
