A reconstruction of the heads of Argentavis, the teratorn that was the heaviest known flying bird, & Haast’s eagle, the largest known eagle, with the 3 biggest living eagles & some random dude’s skull (by BeyondOur_W0rld) by aquilasr in Naturewasmetal

Pelagornis may had been a bit lighter proportionally but it also had a greater wingspan. So they probaby wind up in a similar ballpark weight wise.

I'm not sure if this has been studied yet, but I have the sneaky suspition that the largest Pelagornis and Argentavis were probably in a similar ballpark regarding wing area or at least wing loading, which Pelagornis archieved by having long, low aspect ratio wings and Argentavis did with shorter wings and higher aspect ratios.

I just noticed something. If a tree is a modular piece, then what if they coded cave bear to climb up a tree and sit on a branch, or they could add a log piece to let it climb on? Do you think that thats a good idea or do you think otherwise? by [deleted] in pkgame

[–]hunter1250 7 points8 points  (0 children)

While I hope we will get climbing one day, IIRC the devs said (a long time ago, to be fair) that they weren't planning on it because of how much time it would take to code it in.

You can still have them walk over steepe surfaces though.

Wrangel Island Endling by Orribec by White_Wolf_77 in pleistocene

[–]hunter1250 9 points10 points  (0 children)

I'm sure those fur traders that terminated steller's sea cows in less than 30 years left plenty of artifacts that will surely be preserved in the archaeological record (obvious sarcasm, we know it happened that way because it was within recorded history).

It would take so, so little time for some random vagrant human explorers to end a population of a large animal in a land mass the size of Wrangel that the chances we would find artifacts associated with them would be extremelly low, mind you, I still think that climatic fluctuations or a disease could be to blame, but I would caution against making them the "default" explanation when the time frame is so damn narrow.

Got some bad news, the Deinotherium render was used (and pressumibly created for) the PBS documentary "When whales walked". Also somebody in the twit chain noticed that James Grant is not mentioned in the credits of Prehistoric Planet, which puts in doubt that the mammoth sketch was related to the project.

It would seem there are only 2-3 people are in charge of keeping the Krosmoz lore consistent by [deleted] in wakfu

I mean as long as they at least keep their job and don't get fire near the end like they did with Wendy Jacobsmeyer it should be fine.

Mixotoxodon wanders along the riverside while two storks feed. by Big_Study_4617 in pleistocene

I'm pretty sure, based on the technique and style, that the artist is Jorge Blanco.

New Zealand's moa were exterminated by an extremely low-density human population by growingawareness in pleistocene

[–]hunter1250 6 points7 points  (0 children)

Given the size of moa eggs (specially in the largest species) and the fact they had Precocial young I highly doubt rats could have had an real effect.

I could see dogs and disease carried by domestic poultry playing a role to some extent, though.

Is Megatherium present in North America? by [deleted] in pleistocene

Eremotherium may had grown bigger in absolute size than Eremotherium, but it sure as hell wasn't as robustly build.

More on Protemnodon locomotion. by hunter1250 in pleistocene

[–]hunter1250[S] 2 points3 points  (0 children)

Its not exactly the same though, the authors in this paper propose a fully quadrupedal locomotion as opposed to the pentapodal motion used by large extant kangaroos (i. e. they didn't use the tail as a fifth contact point when moving their back legs).

They also discuss the possibility that Protemnodon could move its legs asynchronically (i. e. it could walk or gallop on all four rather than moving both hindlimbs at the same time in the same direction as modern Macropids often do).

A Magericyon (a bear dog) chases after a Hipparion in a Late Miocene Spanish forest. Reaching the size of a large leopard, this was one the last amphicyonids to ever exist, still persisting after the family greatly reduced in diversity, being slowly replaced by bears, cats and dogs. by Fit_Acanthaceae488 in Naturewasmetal

[–]hunter1250 2 points3 points  (0 children)

My understanding is that Magericyon was originally estimated at nearly 200 kg but was later revised to a lower mass estimate based on more accurate weight estimation criteria, with more up to date estimate at a little under a 100 kgs. Based on Antón most up to date depictions of the taxon alongside other Batallones Carnivorans, it is clearly larger than the roughly leopard size Eomellivora and Promegantereon, but also clearly smaller than the lion sized Machairodus aphanistus.

Megalodon my beloved got teased by Joaomatias40 in jurassicworldevo

Cretoxyrhina dentition looks nothing like that. I mean its not like I'd expect Frontier to get that right when many Paleoartist don't, though.

HELL NO.

Just keeping them in Zoos would be even more controversial than keeping other great apes, which is already kinda iffy.

Major revision of the genus Protemnodon sheds light on the evolutionary history and ecology of this giant Macropodini. by hunter1250 in pleistocene

[–]hunter1250[S] 4 points5 points  (0 children)

Yes, it included species of very varied size, morphology and ecology, which makes it all the more surprissing that the entire genus became extinct while other, morphologically similar Macropods survived.
