The Min/Max values are calculated for a Pokémon at level 100. Maximum values are based on a beneficial nature, 252 EVs, 31 IVs. Minimum values are based on a hindering nature, 0 EVs, 0 IVs.
Tiers are calculated from the Pokémon with the highest available stat for that stat. Example: Blissey has the highest base HP at 255, so all tiers are divided by 6 from 255. Whereas the highest DEF is calculated from Shuckle at 230. This shows a better representation of where a Pokémon's base stat lies compared to the highest that stat can be. The length of the stat relative to the Tier also shows where it sits inside the Tier.

Pokédex entries:
Omastar
red-blue
A prehistoric POKéMON that died out when its heavy shell made it impossible to catch prey.
yellow
Sharp beaks ring its mouth. Its shell was too big for it to move freely, so it became extinct.
gold
Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides.
silver
Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.

Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct.

OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.

Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites.
leaf-green
Despite having strong fangs and tentacles, it went extinct when its heavy shell made it unable to catch prey.
