The large beast ever to have walked on Earth were the long - necked , long - taileddinosaursknown as sauropods , and the most famous of these giants was likelyBrontosaurus , the " thunder lizard . " For more than a century , scientist stopped using the genus nameBrontosaurus , but in 2015 , researcher evoke it was time to " resurrect " it . So why wasBrontosaurusbrought back from the dead , so to speak ?
The skeleton of a long - neck , long - tailed dinosaur was unearthed in Wyoming by fossilist Othniel Charles Marsh in 1879,according to the Natural History Museum in London . At the time , scientist dubbed the giant plant life eater , which lived during the Jurassic period about 150 million yr ago , Brontosaurus excelsus , according to Yale University .
Brontosaurus was a long-necked sauropod dinosaur.
However , in 1903 , paleontologist Elmer Riggs found thatB. excelsuswas very alike to another dinosaur , Apatosaurus ajax , which Marsh discover in Colorado in 1877 , the Natural History Museum noted . The differences between the dinosaurs appear so minor that scientist decided it was unspoilt to put them both in the same genus , or chemical group of species . BecauseApatosauruswas make first , the pattern of scientific assignment keep its name , run scientists to retire the nameBrontosaurus .

More than 100 age later , researcherssuggested revivingBrontosaurusas its own genus . A2015 studyof sauropods in the journal PeerJ found that the originalApatosaurusandBrontosaurusfossils may have been different enough to class them as separate group .
Brontosaurus was a long-necked sauropod dinosaur.
The virtually 300 - Thomas Nelson Page study examined 477 strong-arm characteristic of 81 sauropod specimens . The initial aim of the enquiry was to analyze the relationship between the species attain up the family of sauropods known as Diplodocidae , which includesDiplodocus , Apatosaurusand , now , Brontosaurus .
All in all , the scientists launch thatBrontosaurus’neck was high - place , narrower and little thanApatosaurus ' , study lead authorEmanuel Tschopp , a vertebrate palaeontologist now at the University of Hamburg in Germany , told Live Science . They suggest three known coinage ofBrontosaurus : B. excelsus , B. parvusandB. yahnahpin .
" They callBrontosaurus’resurrected,'“Jacques Gauthier , curator of reptiles at the Yale Peabody Museum of Natural History , who did not participate in this survey . " I like the ring of that . ' repair ' is a dead right full term , but ' resurrect ' is the official description of what they have done . "
Tschopp noted that they could not have made this breakthrough 15 or more years before their study ; only of late did finding of dinosaur similar toApatosaurusandBrontosaurushelp reveal what made these groups alone .
It has been nearly a decade since the paper published , and Tschopp noted that " not everybody accepts such proposals immediately . There have been — and still are — researchers who do n’t desire the resultant role quite yet and continue to utilise the nameApatosaurusfor what I callBrontosaurus . "

Mike Taylor , a vertebrate paleontologist at the University of Bristol in England who did not take part in the 2015 study , severalise Live Science in an email , " you rarely get consensus from paleontologists on these matters , so the answer you get will depend on who you call for . There ’s been no pushback in the conventional lit , but I ’ve heard a bit of murmuring . "
Still , to Taylor , the call to " resurrect"Brontosaurus"just feel like a reasonable thing to do . " He noted that the 2015 cogitation " made a solid contention that most specialist found pretty persuasive and not especially surprising . " Taylor and his colleague have mentionedB. excelsusandB. parvusin their ownstudiesa number of clock time .
