Uma ufuna ukuhlala isipiliyoni sokuhamba phakathi izinsalela eziphilayo nengxenye yomlando okude, lapho-ke izwe lase-Australia elingakunikeza lokho nawe. Lapha kukhula olunye lwezinhlobo ezimbalwa ezithathwa njengeziyi "fossil" yangempela emhlabeni, i UPine Wollemi, kwatholakala kungekudala ngo-1994.
Le nhlobo yesihlahla yayisencane edlule 90 izigidi zeminyaka futhi empeleni ingenye yezinhlobo ezindala kakhulu zezinsalela eziphilayo. Namuhla kunezihlahla ezingaphansi kwekhulu zalezi zivuthiwe kodwa zisaphila futhi zisakhula kulesi sifunda esincane sezintaba ezidumile zaseBlue.
Imithi i-Wollemi ikwazi ukuzivumelanisa nezimo kalula futhi ingasinda ezimweni zezulu ezinzima kusuka ku -5ºC kuye ku-45ºC. Zibhaliswe ngokusemthethweni njengezilwane ezisengozini futhi ochwepheshe bakholelwa ukuthi indlela engcono yokuzigcina ukwenza zikhule ngaphakathi ezingadini nasemabhodweni, futhi empeleni lokho kuyenziwa, ukuze zingabi isiphetho sesimo sezulu.
