Ok, so the wife and I are currently having cocktails at Parasol Down in Las Vegas, and our favorite cocktail waitress noted that my very loud shirt had animals on it that really don’t go together- like flamingos and lions and Indian elephants. Not to mention New World monkeys and bears, all in a jungle. But neither of us can recall the word for such a mess. Anachronistic means time-different. Geo something? A little help before the ice in my Manhattan melts?
I don’t know the word you’re looking for (or if it even exists), but it suggests one of my pet peeves – people mixing up dinosaurs from different locations and different eras. Fantasia notwithstanding, the T. Rex didn’t live at the same time as the Stegosaur, or the brontosaurus/Apatosaurus. (It could’ve fought with a Triceratops, though – they lived in the same time and place). The ubiquitous predator of the time of the stegosaur was the allosaurus, which was much smaller, and could reach its mouth with its forelimbs.
Most people know better than to put dinos with cavemen or wooly mammoths, but they tend to lump all the dinosaurs together.
Your OP suggests those Gary Larson cartoons that show penguins and polar bears together.
TV Tropes simply calls it Misplaced Wildlife.
Isn’t “incongruous” the word?
ETA: “adventitious” can mean “not native”, but I don’t think that’s quite what you’re looking for here.
Anomalous is a much broader word, but would fit in your case, as well as other circumstances.
Geographically incompatible?
Geographically disparate?
Geo-distributed?
Geo-Illogical?
Disney.
Garish?
flees
Rocks which appear outside of their origin (as in, e.g. moved by a glacier) are allochthonous.
Animals that appear foreign to their native area are adventitious.
But I don’t know of a word to describe a group of such other than the aforementioned incongruous.
Having said that:
While the New World monkeys & bears may be out of place, all the other animals could be found, if not together, at least in close proximity, in NW India, in/near a jungle - Gir Forest NP hosts the only remainingAsiatic Lion population, and the Flamingo Islands in the Rann of Kutch are nearby. There are no wild Indian elephants in that area AFAIK, but it wouldn’t be totally weird to see them in that vicinity. Also, of course, Indian monkeys and bears.
And Dinosaurs, just for** Cal** 
.
I love xkcd’s illustration of the* T. rex*/Stegosaur phenomenon.
Which lends credence to my theory that dinosaurs tasted like chicken.
I’d say it’s the exact word, even if common usage has a very slightly different twist (more “weird” or “unexpected”). But things that don’t fit together are indeed non-congruent, or incongruous.
But perhaps your shirt just depicts a zoo?
Anatopesthesia? An error in location, as opposed to anachronism, an error in time.
“Hot Mess”.
Gondwanan? Or Pangean? As in, of or from the supercontinents?
Ostrich is more like the best beef fillet (only cholesterol-free), and I’d rather use the biggest modern dinosaur as a guide to what Cretaceous dinosaurs tasted like. Which would be: damn tasty, especially with a port wine sauce.
Here you go. He didn’t say they were on the shirt; were the lions scratching?
Yeah, I know fleas has an “a” in it.
Are you just looking for the word “menagerie”?
A menagerie is a collection of captive animals, silenus is looking for a term for a anomalous grouping in the wild, it looks like.
