Well, as I understand it, the vast majority of coal comes from, well, the carboniferous (litt. 'coal-bearing') and also from the permian. Dinosaurs didn't exist at that time.

Petroleum is found in sedimentary rocks, and is mostly zooplankton and algae. You know, sediment. Zooplankton is indeed animals, but things like fish eggs and small larvae of various stuff. For petroleum to form, organic matter needs to settle to the bottom of a body of water and decompose without oxygen.

Dinosaurs don't tend to do that in large amounts, for a couple of reasons.

1: Dinosaurs are vanishingly small percentage of the biomass of an ecosystem, especially compared with plants

2: As far as I know there were no (fully) aquatic dinosaurs, so it's not a likely place for them to die to begin with

In conclusion, saying that fossil fuels are made of dinosaurs is about as correct as saying that peanut butter is made of flies because the occasional fly part might be in there. It's misleading. I'm not a paleontologist or geologist, so feel free to correct me ofc, but I'm fairly confident it's not dinos lol

There are more pressing problems. You shouldn't use fossil fuels because they're polluting anyway, but veganism is about not harming animals by encouraging exploitation by using their products.

Oil and gas come from ancient plants mainly, and you are not harming the ancient animals by using their fossils even if it did come from animals.

Time for a proof by induction: Base case: if you use only one wipe and it looks clean, you won't trust it and you'll use a second one. Now assume that you need n+1 wipes to realize you needed n wipes.

If you needed n+1 wipes, by the inductive hypothesis you will take (n+1)+1=n+2 wipes which proves the hypothesis

Q.E.D.
