Sea Horses (and Pipefish & Sea Dragons) are not true fish...they split from the backboned family somewhere between the Hagfish and the Lamprey.
Then why do we only find that particular group in the fossil record about 30 million years back? last I heard, we don't really have hagfish fossils, and I suspect its nearly the same for lampreys (Tulley Monster being one rare exception or not)...so its not really surprising.

Projects Punga: A terraformed world with no vertebrates Last one crawling: The last arthropod
ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)
Potential ideas- Swamp world: A world covered in lakes, with the largest being caspian sized.

Quotes "Arthropod respiratory systems aren't really "inefficient", they're just better suited to their body size. It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif

Basal stegocephalians, lissamphibians, temnospondyls, lepospondyls, reptiliamorphs, synapsids, and sauropsids all come from different fish and evolved tetrapod characteristics independently. This renders tetrapoda highly polyphyletic.

Gigantopithecus was actually an offshoot of Australopithecus that travelled out of Africa and into Asia around six million years ago meaning it was more closely related to humans and chimpanzees then modern day pongine.

Scansoriopterygians were beginning to do fairly well, and, if birds hadn't begun to rapidly diversify, could have competed with them and crossed the Kt-P border.

Vertebrates didn't evolve by natural selection. Our whole body actually arose from massive serial endosymbiosis:
- our bones are calcified colonies of foraminiferans; - our teeth are barnacle-like arthropods that extend feeding appendages in the jaws; - our intestine is a huge Ascaris-like worm feeding on the food that passes through it (maybe also our blood vessels); - our retinas are films of algae, and the rest of the eyes are a matrix secreted to filter dangerous radiations (and eyelids are chiton-like mollusks that graze it); - our tongue is a Cymothoa-like symbiotic slug; - our blood is a liquid multi-species biofilm; - our skin is silk woven by a colonial mites that lives just beneath it (dust mites appear to feed on skin flakes, they actually hatch from them); - our hair are pin mold sporangia; - our mitochondria are aerobe bacteria engulfed by our cells, with their own independent genome; - our brain is a writhing mass of Toxoplasma-like parasites, and our psychology is the sum of the thousands of behaviors they compel; - our nerves are extensions of this mass that carry their will(s) to the other organisms, sort of like the tendrils of a slime mold; - our gonads are highly derived tunicates (the only chordates that actually exist as species) degenerated to germinal cells (the uterus is a giant sac fungus that hosts the female tunicate eggs if its adequately fed by the secretions of the priapulid that transmits the gametes of the male one).
I could go on like this all day.

Naw, ammonites had tentacles, considering we know how many tentacles they had (30). What everyone is wrong about though is that their shell opening was properly positioned above the shell instead of like nautiloids.

Bivalves aren't mollusks but actually derived brachiopods

Projects Punga: A terraformed world with no vertebrates Last one crawling: The last arthropod
ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)
Potential ideas- Swamp world: A world covered in lakes, with the largest being caspian sized. Nematozoic: After a mass extinction of ultimate proportions, a single species of nematode is the only surviving animal. Tri-devonian: A devonian like ecosystem with holocene species on three different continents.
Quotes "Arthropod respiratory systems aren't really "inefficient", they're just better suited to their body size. It would be quite inefficient for a tiny creature that can easily get all the oxygen it needs through passive diffusion to have a respiratory system that wastes energy on muscles that pump air into sacs. (Hence why lungless salamanders, uniquely miniscule and hyperabundant tetrapods, have ditched their lungs in favor of breathing with their skin and buccal mucous membranes.) But large, active insects already use muscles to pump air in and out of their spiracles, and I don't see why their tracheae couldn't develop pseudo- lungs if other conditions pressured them to grow larger."-HangingTheif
"Considering the lifespans of modern non- insect arthropods (decade-old old millipedes, 50 year old tarantulas, 100+ year old lobsters) I wouldn't be surprised if Arthropleura had a lifespan exceeding that of a large testudine"-HangingTheif
"Humans have a tribal mindset and it's not alien for tribes to war on each other. I mean, look at the atrocities chimpanzee tribes do to each other. Most of people's groupings and big conflicts in history are directly or obliquely manifestations of this tribal mindset."-Sceynyos-yis
"He's the leader of the bunch You know his Coconut Gun is finally back to fire in spurts. His Coconut Gun Can make you smile If he shoots ya it's firing in spurts. His Coconut Gun Is bigger, faster, stronger too! He's the gun member of the Coconut Crew! HUH!
C.G.! Coconut Gun! C.G.! Co-Coconut Gun! Shoot yourself with a Coconut Gun! HUH!"-Kamineigh
"RIP, rest in Peytoia."-Little
"In Summary: Piss on Lovecraft's racist grave by making lewds of Cthulhu and Nyarlathotep.
Then eat arby's and embrace the void."-Kamineigh
