Oh look you actually took the time to make one of these at last xddd

Pliosaur
Crab
Monkfish

Bullet Ant: Cheap for a Teir 2, basically a ground-bound Hornet. It wouldn't have Dig like regular ants, but it would pack a nasty Poison Sting attack.

Giant Centipeid: T-3, size 2, but tough for its size and with a nasty bite. Maybe put Poison on the bite just for accuracy's sake, but no good abilities beyond that, lest it become too powerful.

American Bullfrog, Goliath Frog, or some other "mouth with legs" style amphibian: small, but bulky, with Leap Attack and a strong bite, and of course make it amphibious. If you could make abilities, I would suggest one where it regains a bit of healt with every kill, to symbolize their habit of eating anything and everything they can, but in leau of that you could just slap Regeneration on it.

hummingbird, seasnake, red panda, panda, jaguar, squrrel, lemaur monkey, starfish (not sure how this would work, but hey why not?}, butterfly, nile crocodile, crane, i still would love to see dinosaurs done somehow.

I think, as far as missing roles in the game, it would be nice to have another Hard Shell creature, a fast unit with no leg attack, an amphibious ranged unit, and another Overpopulation creature. More ealry-game creatures would be cool too.
I'd recommend a Galopagos Tortoise, which sacrifices the Snapping Turtle's amphibiousness and bite for lower cost and a larger size.
Something like a Pronghorn could fill the other role, which would be nice for fast ranged units.
A new frog could be an amphibious ranged unit, more traditional than the Pistol Shrimp.
Something like a Salmon as an overpopulation unit. Basically anything different enough from a Lemming would work, though.

My brother had a more creative idea, though- a Beaver which is able to construct bramble fences. I'd also personally like to see a Moa as a large level-4-type creature with a strong back-leg attack.

I think there should be a Wildebeest, which will have the ability of herding & horns. It might be good for a unit that will have an ability to form larger herds.

I also think there should be a macaw, because Tellurian needs more birds. I don't think it needs abilities.

I do also want a Flamingo, again, because of more birds. I'm unsure about what abilities it will have.

And at last, I think there should be a Pufferfish, which will be like an aquatic version of the ingame porcupine.

how about flying bats? We need monetreems too

You mean like the bat that's already in the game and also flies?

xddddddddddddddddddddddddd

yeah but it is a pygmy version with a pig like snout

This sounds incredibly similar to the Musk Ox, making the creature very redundant.

While that would look interesting, it wouldn't be very useful from a strategic perspective.

I have actually somewhat wanted a Flamingo in the past, because it could be a medium-sized hovering unit.

A Pufferfish would be quite useful. It could have quill burst AND poison touch. I support this idea.

Raccoon: teir 2 creature being size 2 with 2 attacks being bite and scratch
Brontosaurus: teir 5, size 9, atks: bite and tail whip
Gazelle: teir 3, size 3, attack: Gore, skills: Herding & Charge Attack
Beaver: teir 2, size 2, attack: Bite and is amphibious

Texas horned lizard
https://en.wikipedia.org/wiki/Texas_horned_lizard

size 1
direct range dmg (could be same effect as velvet worm but red, cos its shoots blood)
high defence (horns are parts of sceleton) ~45
regen (cos lizard)
frenzy (he shoots blood at enemies, making himself weaker (blood lost) and high blood pressure (kinda frenzy thing)) also that would give nice range/frenzy units
could get horns on head cos "horned" <- more fun or kinky stuff then real thing

https://en.wikipedia.org/wiki/Erinaceus
Hedgehog

a size 1
similar to porcupine but without range attack and attack on tail,
and small dmg on head
digging on front legs (he hides in burrows)
quill burst (he is a hedgehog)
keeps disorinetig barbs on tail

this would result with animal similar to skunk (focus on utility) but with different stats (slower, less dmg, more resilient)

How about a few dinosaurs?

Trex: level 5, frenzy, Loner

Triceratops: Level 4 gore, charge, herding, high armor.

Raptors: Level 3, pack hunters

Ankylosaurus: Level 4, armored, immune ,
