Doedicurus
The armadillo-shaped mammal designated as doedicurus (a.k.a. doed) is helpful to harvest stones including obsidian, or as an rolling transport. It's well protected by strong shell and ability to crawl into the ball after having 2/3 damage.
To make its taming faster you can use dilophosaurus kibble for feeding it. Doedicurus usually inhabits around the Grand Hills, Frozen Tooth or Red Peak regions of The Island.
Therizinosaurus
The one of the most risky dinos in the Ark: Survival Evolved. It's the very clever pet useful in collecting wood, meet, berries and etc. as well as battle support. Therizinosaurus lives on the beaches. For easier taming follow few rules: be bountiful about tranquilizers and drugs, keep distance, give megalosaurus kibble or vegetables.
Argentavis
The safest way to travel around the Ark and even move small animals to make their domestication easier. The argentavis is tougher, more healthy and better armed than the pteranodons, so smaller speed makes no sense. The best food for taming is an stegosaurus kibble and raw mutton. Argentavis usually inhabits around Far�s Peak, up near the north-east angle of the map.
Quetzal
An another flying mount you may tame. You can transform it into a flying base by platform saddle and arming it with turrets. Also it can transport farming animals (like ankylosaurus or doedicurus, which can not be transported by argentavis). Just build a few forges on its back and you get own artillery battery. The most difficult thing in quetzal domestication is incessant flying, so for its taming you either have to use a flying mount, or chunk tranquilizers from the tapejara's passenger seat. Be sure to pack some of T-Rex kibble or raw mutton before starting hunt. Otherwise the quetzal domestication will fail.
T-Rex
T-Rex (Tyrannosaur Rex) is one of the most dominant predator on the Ark, having a plenty of stamina and health when compared to other predators. Also you can take it into all boss arenas. For T-Rex domestication you better to build a hunting platform and shoot darts with tranquilizer from it, or use a mountain cliff. Keep in a distance and feed it with raw mutton meat or pulmonoscorpius kibble.
Mammoth
The mammoth is valuable tamed animal due to its wood gathering talent and high damage ability. That a great walking fortress is significantly faster and more portable being compared to the brontosaurus and diplodocus. Feed mammoth with vegetables or raptor kibble and use tranquilizer darts for taming.
Ankylosaurus
A prickly dinosuarus with a mace on a tail can collect a lots of metal, crystal and flint, making it cheap for mining. The ankylosaurus is very easy to domesticate due to its slow movement. Feed it with dilophosaur kibble.
Carnotaurus
Fast mid-range predator which brings much more damage compering to a raptor. It's very valuable in meat harvesting for your other domesticated animals. Feed it with ankylosaurus kibble. Taming is easy but stay in a safe position to avoid aggression. You may find wild carnotaurus on the Dead Island, Northeast Shores and Redwood Forest.
Ichthyosaurus
An easy-to-tame excellent diver. Its faster than megalodon and appear as the great helper in pearl harvesting. For ichthyosaurus domestication just place dodo kibble to the last slot on your hotbar, it should be enough to get one tamed in short time.
Beelzebufo
Beelzebufo it the giant amphibian from swamp. It is valuable as a taming bracing due to its aptitude to torpor the victim. Another good feature is farming a lot of cementing paste and chitin needed for base upgrade. For beelzebufo domestication aim to it from a rock, cliff or large distance. Raw mutton and pulmonoscorpius kibble are good for quick taming.
