I've seen some of the ones you've mentioned. (Apparently
Maraapunisaurus and
Amphicoelias are synonymous now, the former is the newer name while the latter is the older name, though there's still possibilities of them being slightly different genuses due to the species within them, and Bruhathkayosaurus and Barosaurus are also mentioned in the former article's description comparing sizes, due to being more recently updated than the latter article)
I could post articles mentioning them here for more information:

Also:
I'mma post the main articles for different types of armour, weapons and vehicles here:

(mostly the bombsuit and NBC suit, but the spacesuit could technically also be considered since they use similar materials in certain components to protect against radiation and micrometeoroids and the like)
