No, but there were Mastodons* which scientist believe they coexisted with sabertooth cats.
The only animals that Rolf saw were rabbits, orangs (if they are even animals), owls, penguins (PSiv), moles (PSiv) and Musk Cats. Maybe there wasn’t a good dialogue between the responsible for the script and the designer.
script: okay... here you'll draw a dezorian cat (musk cat)
designer thinking: dezorian (ice planet) cat.... hmmm ok
[a few days latter]
designer: ok, how does it look?
script: :\ hmm.... fine, it's... fine.
Another thing is the introduction of Dezoumans, I mean the brown dezorians that seam like a cross between palmans and dezolians. It must also be summer in Dezolis since there's no trace of ice/snow anywhere.
Summer is very unlikely; the only possibility is that Motherbrain started to punish palmans rebels because they were conspiring against her - and since Dezo seams to be their hiding base/planet (like planet Hoth in Starwars) she re-configured Dezo's climatrol.
So, between AW1268 (PSadventure) and AW1274 (the crash between two ships), a period of 6 years, Dezo became an ice planet again. 7 years later there was a gas leak. It could also be between AW1268 and the departure of Parmans (after the gas leak accident). [I hope no one brings me a screenshot of ice from PSadventure now that I said all this... I didn't investigated yet if this theory is possible, I have to think more about it]

* Elephants (PSI and PSII) were probably the seed for Igglanova, I think.
