Editing Diprotodon (section)

===Fossil evidence===
Despite the role the first Aboriginal Australians are speculated to have had in the extinction of ''Diprotodon'' and other mammalian megafauna in Australia, there is little evidence humans used them at all in the 20,000 years of coexistence. No fossils of mammalian megafauna suggestive of human butchery or cooking have been found.{{efn|The only potential direct evidence of human and mammalian megafauna interaction (that has not yet been revised) is a tibial fragment with a single notch belonging to either ''Sthenurus'' or ''Protemnodon'' (short faced kangaroos), identified in 1980 by Australian zoologist Michael Archer and colleagues in [[Mammoth Cave (Western Australia)|Mammoth Cave]], Western Australia.<ref>{{cite journal|last1=Archer|first1=M.|last2=Crawford|first2=I.

In 1984,  Gail Paton discovered an upper-right ''Diprotodon'' incisor (<sup>2</sup>I) bearing 28 visible cut marks in Spring Creek, south-western Victoria; Ron Vanderwald and Richard Fullager studied the incisor, which was split in half longitudinally, seemingly while the bone was still fresh but it was glued together before Vanderwald and Fullager could inspect it. Each piece measures {{cvt|40|cm}} in length. The marks are aligned in a straight line, and measure {{cvt|0.91–4.1|mm}} in length, {{cvt|0.14–0.8|mm}} in width, and {{cvt|0.02–0.24|mm}} in depth. They determined it was inconsistent with bite marks from scavenging ''Thylacoleo'' or [[Muridae|mice]], and concluded it was incised by humans with flint as a counting system or a random doodle.<ref>{{cite journal|last1=Vanderwal|first1=R.|last2=Fullagar|first2=R.|year=1989|title=Engraved ''Diprotodon'' tooth from the Spring Creek locality, Victoria|journal=Archaeology in Oceania|volume=24|issue=1|pages=13–16|doi=10.1002/j.1834-4453.1989.tb00201.x}}</ref> This specimen became one of the most-cited pieces of evidence humans and megafauna directly interacted until a 2020 re-analysis by Australian palaeoanthropologist Michelle Langley identified the engraver as most-likely a [[tiger quoll]].<ref name=Langley2020>{{Cite journal|last=Langley|first=Michelle C.|date=2020|title=Re-analysis of the "engraved" Diprotodon tooth from Spring Creek, Victoria, Australia|journal= Archaeology in Oceania|volume= 55|issue= 1|pages= 33–41|doi= 10.1002/arco.5209|issn=1834-4453|doi-access=}}</ref>

In 2016, Australian archaeologist Giles Hamm and colleagues unearthed a partial right radius belonging to a young ''Diprotodon'' in the [[Warratyi|Warratyi rock shelter]]. Because it lacks carnivore damage and the rock shelter is up a sheer face ''Diprotodon'' is unlikely to have climbed, they said humans were responsible for taking the ''Diprotodon'' to the site.<ref>{{Cite journal|last1= Hamm|first1=G.|last2= Mitchell|first2= P.|last3= Arnold|first3= L.J.|last4= Prideaux|first4= G.J.|last5= Questiaux|first5=D.|last6=.Spooner|first6= N.A.|last7= Levchenko|first7= V.A.|last8= Foley|first8= E.C.|last9= Worthy|first9= T.H.|last10= Stephenson|first10= B.|last11= Coulthard|first11= V.|date= November 2016|title= Cultural innovation and megafauna interaction in the early settlement of arid Australia|url= http://www.nature.com/articles/nature20125|journal= Nature|volume= 539|issue= 7628|pages= 280–283|doi= 10.1038/nature20125|pmid=27806378|bibcode=2016Natur.539..280H|s2cid=4470503}}</ref>
