A paleontology shitpost.
Combination of shitpost and coprolite, the scientific term for fossilized shit.
Did you see the newly discovered Dinosaur?
Yeah, people are coproliteposting about it already.
A cute bastardization of birb, itself a cute bastardization of bird, the only dinosaurs left after the Cretaceous-Paleogene extinction.
Look at that cute borb! So round, so smol!
