These things in packs can take down rexs, and carnos. Reason being because of there small hit box and high damage. And in packs they can melt many dinos.

Get one of each gender and breed a whole army

One time my dimorph just ran off for about a week. When I found it it had 3 stacks of raw meat and 9 raw prime

These little creatures are amazing for clearing caves just get about 20 of them drag them into a cave and watch them work you need to pay attention to there hp though there strength is in numbers so individuals can die

Best tame for the time and narcotics. I have about 20 of these above lvl 200 defend my base.. They shred people along with my turrets. I also raid with 10+ of them. They make shooting at me impossible as they swarm people not their mounts. Use the spyglass to scope dinos or people and whistle attack target. It is an invaluable sniper tool.
P.S. Keep them close to your fabricator and smithy to level faster.

I had a pack of 15, roughly level 220+ mostly second generation beasts. All at 2500ish health and 300+% melee damage. They'd kill wild 150 rexes and brontos in a couple seconds. They're all now rip when I thought they'd work on a level 15 giga... woops.

These little guys are great for base Defence. The first technique I mostly only use to defend against quetzals is strapping C4 to a low level dimorph, then whistle him to attack the quetz, and trigger the C-4. Just as he's closing in to bite the quetz. You might need four or five of these guys to down the quetz, but if you ask me, 5 10 minute tames are worth it for a game that probably took the opposition a few hours to tame. Another technique like to use to take out rexes gigas, and other tanky dinos, is go around, behind them with a swarm of dimorphs (don't do this against Brontos or any Dino with a huge AoE attack) Then whistle attack (which is ".") on the rider. They will shred through him so fast, he won't know what even happened. After the rider is off, you can easily trap the giga in a large bear trap, kite it off a cliff (or away from your base) or just kill it, when the Dino doesn't have a rider, it sacrifices attack speed which is a very vital part of PvP.

Always have one it saved my life countless times is you pump its lv up points into atack damage and hp it will save your life if you get knocked out by a noob it will shred them apart

Great when wondering around collecting things. If you get in a battle they will help. Hope this helps

If you upgrade weight, it makes a great mini-fridge for your shoulder, since it causes food to last twice as long, like other dinos.

My dimorphodon always steals the kill

Highly underestimated tame, great damage potential. Keep on your shoulder and triple your damage factor whilst riding Pter others. Also will attack close range targets so you don't whack your dinosaur on accident. Also, can load excess weight onto it because 50% conversion rate to your carry weight

Great for destroying beehives, grapple up to the beehive with a Dimorph on your shoulder and use a sword on the beehive, the dimorph with kill almost every bee that attacks you from your shoulder.

Get several high levels and Make them follow something such as a dodo, put them in a tall, open building on aggressive and drop wild dinos in the pin to level them up. And when war breaks out, make them follow a tank so they can knock flying people off their tames. (Idea from sl1pg8tor)

Are not affected by oxygen while on your shoulder, so it helps you to find your body if you die because it will be flying right above the water where you died. Also if attacks while on your shoulder, so it can collect bodies for your herbivores, help keep attackers off of you, and can be thrown at Dinos do kill them. There is no reason not to carry one, they are very helpful.

They can fly through windows, so if you want a cool base defense set up 1x1 boxes of windows and fill them with these guys

I tamed one of these that was level 30, put it on my shoulder and forgot about it. Until I was attacked by a lvl 22 sarco. I got tossed off a cliff and my little shoulder decoration flew up and eventually killed the sarco by itself!!! Saved my butt

Take a turtle with high health, put it on passive and wandering, then make your dimos follow it. Lots of levels for the dimos.

Artifact mass collection - Dimorphadons are accessible to every cave, and every Dimorph can carry an artifact, the Artifact crates don't take long to respawn, so camp there for a little and make sure every player/dino has an artifact on them before leaving the cave, you'll have plenty of artifacts to display and use to summon bosses multiple times from doing each cave just once!

They are best for ice queen... just Push hp to 3k, Rest dmg and you‘ll should be fine... whistle them aggressive in cave and all you need is a shield... they also breed faster than anything I’ve seen so far, and drop eggs faster than any dodo would...
