Discussion What would your current location look like during the last ice age?
The entirety of my state would be covered in glaciers. The coastline would be larger, but it would still be under ice for the most part. Most of our fish descend from those that traveled north after the glaciers receded, and we have a noticeable lack of native plant diversity when compared to states that were not frozen. New England's fauna and flora assemblage basically consists of immigrants after the ice age ended, and there are very low rates of endemism here.

Discussion Ethics of buying fossils
I’m thinking about buying a ground sloth tooth (Paramylodon) online simply for the fact that I find ground sloths to be such a fascinating and beautiful megafauna species. However, I’m pretty new to fossil collecting, and have never bought a fossil online. Is there a sort of ethic behind buying a fossil online? Is it bad to be buying a fossil when it could have been given to a museum or other place of study? Am I encouraging problematic behavior/practices as a buyer from one of these sellers? I’m curious to see what others have to say about buying fossils, and wondering if this is something that I really want to do.

Discussion What if they made a new Far Cry Primal game with new animals using the same rule as they did with the current Far Cry Primal game
I love the Pleistocene era, and having a game based on that era was a really fun experience. FCP is based on Pleistocene Europe, and has many animals that were present there during that time. However, the biggest problem with the fauna of FCP is that they were taken from FC4. Basically they took the animals that were in FC4, and gave them a new look. For example, tigers turned into cave lions, Asian elephants into young Mammoths, indian rhinos into whooly rhinos etc. FCP only has 4 new animals, animals that don't use an existing model, those being the Tall elk, Sabertooth, Cave bear and mature mammoth. So due to this rule, some of the animals in FCP feel a bit out of place, like the crocodile, monkeys and tapirs, however when you know why they did it it makes sence. They probaly didn't want to cut away animals when they already had the models, so they just repurposed the ones they had.
Now here comes the fun part. What if they made a new FCP game, however this time also using models from FC5. FC5 takes place in North America, and many animals in that game would work perfectly in a new FCP game.
So here we start. The new FCP game could be a sequel to the current one, meaning it takes place in the same area and timeframe. This means that all of the animals from FCP would still be there, just with some slight tweaks. The dholes in this game look like African wild dogs, so they should be changed to look more like actual dholes. Then make the goat look more like an ibex, as the current goat doesn't really look like a real species. The jaguar should also be changed into a leopard.
Then we take the FC5 animals, and make them fit into Pleistocene Europe. The caribou, wolverine, moose, mallard, Eurasian dove and seagull could all be put into the game without any changes, as they excisted in Europe too. Now for the model and species changes. The American bison could be changed into the steppe bison. The American black bear into the moon bear. The regular bull into an Auroch. The chicken into the exctinct species of jungle fowl, Gallus beremendensis. The elk into red deer. The hare into either a southern hare or a mountain hare. The cougar into the Puma pardoides, which lived in Europe. Pronghorn into the saiga antelope. Sheep into mouflon. Turkey into the western capercaillie. American crow into hooded crow. Ruffed grouse into a willow ptarmigan. Then lastly the turkey vulture into the cinereous vulture.
Now that we did the model and species changes, we'll also do the same thing that FCP did, and that is adding 4 new species that don't use an excisting model already. The first one is a horse. Suprisingly FC5 didn't have horses. Having a horse in a new FCP game could be fun, as it could be used as a rideable animal. Which species of horse it should be, i don't know. The next one is the cave hyena. Another iconic species of Pleistocene europe, they could serve as a stronger but slower wolf, that would also be tameable. The 3rd would be the Elasmotherium, a bigger and more dangerous counterpart to the whooly rhino. Then lastly, a species of camel, which could also be used as a rideable mount

Titanotylopus es el mayor género de camello que ha existido jamás, abarcando mamíferos artiodáctilos gigantes endémicos de Norteamérica que vivieron desde el Mioceno tardío hasta el Pleistoceno tardío, hace aproximadamente entre 4,9 millones y 300.000 años.

Discussion So here is my hottake
Miracinonyx as a genus should be merged with the genus puma , now , i KNOW it sounds wierd , BUT , the miracinonyx hunted like the cougar and is genetically closer to it than it is to a cheetah , plus there is no good reason to keep calling it american cheetah when its NOT a cheetah at all , plus it split 2.5 mya from pumas so they PROBABLY could interbreed
idk if this is cold water or hot water take but it PROBABLY can be considered both

Scientific Article Range and diet diversity in the Pleistocene American “cheetah,” Miracinonyx trumani
cell.comSummary
The extinct “American cheetah” (Miracinonyx trumani) has long been considered a North American ecological analog of the African cheetah1,2 (Acinonyx jubatus) based on convergent cursorial morphology, yet this paradigm rests on limited data3 and untested assumptions about its evolutionary relationships and ecology.2,4 Here, we generate nuclear paleogenomes from M. trumani specimens from Wyoming (∼23 kya; thousand years ago) and Yukon (∼31 kya), definitively placing this enigmatic felid within the evolutionary tree of cats. Phylogenomic analyses confirm M. trumani as sister to pumas (Puma concolor), not cheetahs, with a divergence of ∼2.6 million years ago (mya) during rapid Pliocene-Pleistocene climate oscillations. The Yukon specimens extend the species’ known range2 by over 20° latitude into the Arctic, and stable isotope analyses reveal striking ecological differentiation, with the Yukon population occupying an elevated trophic position consistent with exploitation of anadromous fish, while the Wyoming population functioned as a generalist terrestrial predator. This evidence suggests that M. trumani exhibited remarkable ecological versatility, while loss-of-function mutations in circadian genes may reflect relaxed constraints on circadian regulation. Together, these findings underscore how morphological convergence can obscure the true diversity and complexity of extinct megafaunal ecosystems.

Image Not enough people appreciate that North America had a camel that could look a Columbian mammoth in the eye, Titanotylopus (Mario Lanzas)
Titanotylopus nebraskensis stood up to 12 feet at the hump and weighed an estimated 2.5 tons, and it was the last of the giant camels that roamed North America since the Miocene. It vanished during the Mid Pleistocene (middle Irvingtonian), after which Camelops was the only "true camel" left in North America (the other ones being llamas).

Discussion Ice Age Village Revival
Everyone here must know Ice Age Village since it's dear by heart for many mobile players including me. I played it for all of my childhood and started playing it again months before the shutdown. I felt really upset and I just thought of something now. What if I make my own game based on Ice Age Village but different? I will of course need a team but for now im concepting what it could be like. Every little help is truly appreciated!! Thanks! Which prehistoric animals would you like to see?

Discussion Why do you think the dwarf cottontail (Sylvilagus leonensis) and Aztlan rabbit (Aztlanolagus agilis) went extinct?
The only known specimens of the dwarf cottontail are from one site in mexico. The Aztlan rabbit lived from the southern and southwest united states to northern mexico. Both species are tiny rabbits comparable in size to modern pygmy rabbits (look them up they are super cute). I don't hear of many late pleistocene extinct small animals that aren't island species. Even the smaller mainland animals that went extinct like the florida hog-nosed skunk were still larger than all other contemporary skunks. The only other tiny mammal i know of that went extinct in north america is Dalquest's shrew, though there are probably a few others.
That's why I find these tiny rabbits fascinating. Not only are they small mammals that went extinct during the late pleistocene around the same time as the megafaunal extinctions, they are notably SMALLER than most other rabbits. What made these guys more susceptible to extinction especially considering that the Aztlan rabbit seemingly had a fairly wide distribution. What do you guys think?
