This absolutely amazing eohippus figure arrived from the incomparable Kitty Cantrell studios. This creature is 9" long! It's going to be amazing, no matter whether I paint it or not. You can see Kitty's fabulous work at http://kittycantrell.com

All the early mammals looked like rats.

The evolutionary divine perfection.

The archeocete Perucetus colossus dives through a coastal bloom of jellyfish in the Pisco Basin (southern Peru), some time during the Eocene (with bonus multiview).

I originally intended to add epibionts to this reconstruction (reflecting the specialized communities found on many living whales, especially baleen whales). Yet, interestingly, it appears that most animal epibionts and ectoparasites of modern cetaceans, such as whale barnacles (Hayashi et al. 2013) and remoras (Friedman et al. 2013), only appeared in the Neogene or late Paleogene, or have a poorly known (co-)evolutionary history, like whale lice (Pfeiffer 2009, Iwasa-Arai & Serejo 2018) and pennellids (large parasitic copepods) (Hermosilla et al. 2015). So, no epibionts* for big lad Perucetus!

References and notes about the reconstruction:

*animal epibionts. Unicellular eukaryotes like diatoms were most likely present on early cetaceans, given their prevalence on modern large marine animals (Ashworth et al. 2022). Of course, it is possible that other animals (i.e., early, less specialized representatives of modern groups, or different taxa altogether) were also already exploiting the surfaces offered by these early whales; however, this remains entirely speculative.

The reconstruction of Perucetus proposed in its original description (Bianucci et al. 2023) includes some rather odd (if interesting) choices about soft tissues, including limbs with webbed and distinguishable fingers, and a manatee-like tail. While these choices might be defendable in light of the rather basal status of Perucetus among cetaceans, I opted for a more derived look based on the assumption that fully marine cetaceans like basilosaurids would have probably rapidly acquired hydrodynamically favorable adaptations, pushing them towards a more familiar Neoceti-like appearance (even though Perucetus itself was likely a poor swimmer (Bianucci et al. 2023), it seems likely to me that this was a secondarily acquired trait, given the less extreme morphology of other basilosaurids).

Reconstruction in the multiview scaled to ~18 m in length after the estimations of Bianucci et al. (2023).

Did you see the part where Meg was annoyed that only dogs can be qualified to be service medical dogs? lol guess she's mad a bird can't be a service cardic arrest animal. Once again pulled up the "people think only DOGS can be trained to do this!!! How dare they!!!" *grumbling about mammalian bias* argument. I'm sorry Meg but your fucking bird or a rabbit cannot be a service animal for the blind or anything that dogs have be bred to do

me when they won’t let my service crocodile into Walmart:

#Dogs are favored because they have been domesticated for thousands of years and selectively bred for extremely specific behaviors #they also have heightened hearing and smell that can allow them to detect certain medical emergencies early #and because a dog can be predictably trained to not attack someone #yes you can train a Komodo dragon to perform a lot of what is asked of dogs #but as a wild animal guess what #they are more likely to attack someone because they are more likely to perceive normal human behavior as a threat #and even domesticated non-mammals just generally aren’t built for a lot of what a service animal needs #what would a service pigeon do for you exactly #and even if it could do something to help you it’s still a pigeon and if you take it outside there is a very present chance #of a hawk plucking it off your shoulder as dinner #generally don’t need to worry about a golden retriever being carried away by eagles #not to mention dogs being able to be potty trained which. Many animals cannot reliably be #even rodents and other small mammals can’t generally since they don’t have voluntary bladder control

HEY!!!!when splendid wound back time in better off bread, did the idols get to keep the blood from the first time everyone died in that episode, or did the blood get, like, slurped back

OHOHOHOH THIS IS A GOOD ASK

So I had to think about it a bit and uh…yeah I think because it reversed time the original deaths didn’t count. The trio don’t really mess with time other than prolonging how long everyone lives. They have no idea it even happened.

Nergal though did experience some heavy deja vu as he caused Giggles to fall off the ledge and then threw a whole ass meteor at Toothys face that second time. —Side note, this meteor was probably the size of the chelyabinsk meteor (19 meters in diameter) rather than the Chixulub meteor that Nergal wiped out the dinosaurs with (approximately 15000 meters in diameter); the one he threw at toothy was just enough to destroy toothy and the surrounding forest and cause havoc in the town, but not world ending—

Bad luck was already in motion before Splendid got there and made it worse.

Thats why Splendid is considered one of the Isles “catalyst” residents. He’s just another bit of bad luck in motion. And Nergal takes advantage of that when it happens. It’s like Nergal sets up the dominoes and the catalyst comes in to knock ‘em over. Flippy is also often used as a catalyst resident and Lumpy’s amazing mental prowess causes him to end up being one from time to time too. Predominantly full time catalysts are fairly rare on the Isles though. Splendid ignoring the cries for help that second time around didn’t save anyone, it just took away his own involvement in their deaths is all.

Also speaking of time travel, Sniffles totally went all the way back to the DinoSore days when the curse was starting. Probably not too long before the meteor hit and set the curse of the Isles in full swing.

Right image I’d say it’s either a type of ichthyornithiformes, toothed flying birds that lived alongside their non avian dinosaur family members, or a Nemicolopterus, a small pterosaur from the Cretaceous. It died out technically before the end of the Cretaceous but I’m just working with what they give me here. To the right…..look….i have to remember that the people who worked on htf were not trying to be accurate and were just throwing around prehistoric looking animals willy nilly, but that thing looks like a drepanosaurus which was a bizarre little reptile from the Triassic period. I’m just gonna take some artistic liberties and say it’s a surviving member of that lineage that may or may not have existed during the Cretaceous and move on.

And also this guy totally lived in the trios old village and he ends up living in the First Civilization after the meteor impact I’ve decided. He may look like an anteater but he’s actually a gypsonictops. And yep, ants also existed at the time and they probably were eaten by mammals like gypsonictops. Im using Linguamyrmex vladi, the “hell ants”, just as an example cus they are cool.

Medieval serving girl this. 18th century farm girl that. I suck up the last few drops at the bottom of my drink through a straw and suddenly I astral project into the body of a small, long-snouted, shrew-like kind of mammal sucking moisture from a drying out riverbed sometime in the Late Triassic. No worries. No burdens. Maybe bugs.
