 Vertebrates have also been named after Attenborough, including a Namibian lizard ("Platysaurus attenboroughi"), a bird ("Polioptila attenboroughi"), a Peruvian frog ("Pristimantis attenboroughi"), a Madagascan stump-toed frog ("Stumpffia davidattenboroughi"), and one of only four species of long-beaked echidna ("Zaglossus attenboroughi").In 1993, after discovering that the Mesozoic reptile "Plesiosaurus conybeari" did not belong to the genus "Plesiosaurus", the palaeontologist Robert Bakker renamed the species "Attenborosaurus conybeari".A fossilised armoured fish discovered in Western Australia in 2008 was named "Materpiscis attenboroughi", after Attenborough had filmed at the site and highlighted its scientific importance in "Life on Earth".
