Recent research based on bone structure suggests that those mega kangaroos couldn't hop like their modern cousins, they were too heavy. They just ambled along at a slow pace. They reached a height of 2 meters and weighed roughly 200 kg. Their huge size was their protection against predators . Humans arrived in Australia approximately 60000 years ago. These huge animals were easy to hunt. They quickly vanished over time due to hunting. DNA evidence suggests that the first humans to arrive in Australia descended from people who originated from southern India / Sri Lanka .

Guys appearently [Obligatory at this point] that the Spinosaurus might have to be rechange or rearranged once again as the latest publication does indicate that the fsac kk specimen is extremely dubious (well it kinda ressurrects the whole *chimera* situation)

[@miquelescribanoivars5049]

Imagine actually taking what Scott Hartman says about Spinosaurus for granted.

[@thedoruk6324]

@@miquelescribanoivars5049 John Hutchinson from the respectable England university has already said those about the FSAC kk specimens uncertainty. Scot Hartman is only validating is even further. On the other hand Ibrahim has said the calculation of Spinosaurus weight is wrong and the animal could be as massive as 10 to 12 tons so decide yourself

[@miquelescribanoivars5049]

@@thedoruk6324 FSAC kk 11888 is almost certainly not a chimera. It all comes from the same quarry, there is no overlapping material, dorsal vertebra centra fit neatly in size with the caudals and more importantly all bones have the same hystological inferred age and isotopic markers. Meanwhile Stromer himself said in his 1932 publication that Spinosaurus B (the individual Scott based his skeletal on) was most likely a chimera, and the fact that three different furcula were assigned to the specimen is indeed pretty eyebrow rising. Also while I don't doubt Scott's professionalism as an paleontographer he's never eximened the bones himself nor study them directly. There is just no way he knows more about them than the guys he discovered and described them. He was already wrong back in 2014 about the hindlimb elements scaling in the specimen for starters.

@@thedoruk6324 "His publication seems credible so far as credible as the nazars publications" Its a blogpost, no matter how well argumented a peer-reviewed paper it's not. "As the Fsac kk is indeed a debacle of extraction is also highly dubious at best of conditions" Yes, which is why histological and isotopic tests were performed, and those clearly showed they belonged to an individual of the same age, and in the same trophic and climate conditions. Given the lack of overlapping material it is way more likely the belong to the same individual than that were two identical specimens in the same quarry.

@@jameswilliams2075 if the intention is to depict a ferocious creature in a cool way, alright. But if it is to show a real aninal that once lived it is better to show it more relaxed too. Not all drawings of lions and wolves show them grinning and snarling, quite the opposite actually.

I have personally seen 4 Tassie Tigers over the past 10 years. I live on Tamborine Mountain Queensland Australia. Two were very young and playing beside our car. A larger one ran across the road in front of me near the same place and the other was an adult and this one was almost an hour west of here. There was no doubt in each case as they are very easy to distinguish from all other animals
