Snow elves aren't on ESO because they were slaughtered by the five hundred companions that came from Atmora to Skyrim during the first era (if i'm not wrong), the race was considered extinct but some managed to make it to tunnels and dwemer cities where the dwemer told them that if they wanted to live they had to consume a poisonous substance that eventually turned them into what they are in TES V, falmer, it is believed they did this to make them weaker in order to enslave them, after that there was only one known living snow elf during the fourth era that you find in the Dawnguard DLC of Skyrim, but he turned evil and the dragonborn eventually kills him.

The dwemer dissapeared because of Kagrenac using his tools to harness the power of the heart of Lorkhan and power the Numidium (they attempted to make their own god) during the battle of Red Mountain in the first era, it is speculated they became the skin of the Numidium or dissapeared into a different realm but none of it is confirmed, there was only one known living dwemer in the fourth era which you can find in TES III, he explains he was traveling to a different realm when the battle of Red Mountain happened and came back just to see all of his race gone.

The Ayleid were the first settlers of Cyrodiil to stablish an Empire and built the Imperial City, they made the amulet of kings out of the crystalized blood of Lorkhan, they were infamous for enslaving human races which eventually led to the Alessian rebellion in the first era, the humans eventually drove off most of the Ayleid from Cyrodiil and many of them were slaughtered by Pelinal Whitestrake, like the races above there still are some remaining Ayleids found in ESO and TES IV but they are only considered a shadow of what they once were

The Chimer were a race of Aldmer that left the Summerset Isles and embarked on a journey to Morrowind led by Saint Veloth, Azura cursed them when Vivec, Almalexia and Sotha Sil used Kagrenac's tools on the heart of Lorkhan to become living gods when they promised to not mess with the heart of Lorkhan, the curse gave the Chimer dark skin and red eyes, they basically became the Dunmer, only Almalexia and Vivec kept their Chimer traits with Vivec being half Chimer and half Dunmer, I don't think the Chimer are an extinct race since they basically are the Dunmer with a curse, but I'll put it here anyways

Those are the most well known extinct races but there is still some other races that are considered extinct that you can look up like Nedes and Atmorans

And goblins looking more human in ESO is probably not lore related, maybe they just wanted to update the models similar to how some Dunmer look horrendous and blueish in Oblivion and then gray again in Skyrim

Ogres and Goblins are considered to be ''Golbin-Ken'', a term used for beastfolk that consist of Goblins, Ogres, Orcs and Gremlins (gremlins are tiny ''orc-rats'' that rarely appear anywhere in the games, I've only seen one in Redguard when the protagonist turned into one) and Orcs only fall under this category because they are mistaken by a different race of Goblins when they are actually a corrupted race of elves. So yeah, Ogres might be related to Goblins, but they are a different race of primitive beastfolk

That's all I know, if some of my info is wrong anyone can feel free to correct me

Final Q why do goblins seem so much more humanish in appearance and more advanced in eso, and lots of sub species riekling etc.

Well, appearance is just a technical matter. Goblins of Oblivion are even more humanish - tall, walk almost like men and mer (drunken, though). In ESO the Goblins are just perfect, to my taste. And ESO provides a lot of lore on them.

As for being more advanced - well, we actually never see their true life. In Oblivion we watched them doing magic, they were keeping rats as cattle, they had weapons and armor of their own style. They drunk alcohol made by people.

They just had no tents comparing to the Goblins of ESO, but who knows why? Warm Cyrodiil climate? Or we just didn't venture too deep in caves where these tents are supposed to be?

As for Riekling, they are a mistery. They are a race of the North Tamriel. More advanced than Goblins - at least in Solstheim DLC of TES5 Skyrim.

There are also some beast races that are not too well-known: the Imga, an extinct race of ape-folk, the Lilmothiit, an extinct race of fox-folk who once inhabited Black Marsh, and the Bird-men of Cyrodiil. The latter were the ones who gifted the elves with the land that became the Imperial City when Topal the Pilot taught them language/writing.

In addition, there is a race of elves called the Sinistral Mer, or Left-Handed Elves, who fought with the ancestors of the Redguards on the continent of Yokuda before it sank into the sea.

The Sinistral was lost as a race when Yokuda sank under the water most the races that are ancient like your list where pretty much wiped out by the Thrassian Plague Falmer where near wiped out by the Atmorains from Atmora but managed to live onward as Falmer in Skyrim under fround even the Falmer Snow Elves stated that they are getting smater bit by bit but I doubt they where known except by legend in the Second Era.

Exactly. The OP is asking about extinct races.

Why did the Lilmothit have to die!!

I bet they would've looked adorable

I have a feeling that Elsweyr will make cat-elves and half of other Khajiit "breeds" "extinct".

There was a lorebook or npc stating they moved up north of lilmoth i think?
