1. Using the Summon command you will get one having a random level, and spawning right near you.
admincheat Summon <EntityID>
2. To get a specific level and distance, you will need to use SpawnDino command.
admincheat SpawnDino <blueprintPath> <spawnDistance> <spawn-Y-offset> <Z-offset> <dinolevel>
"spawnDistance" is a distance from your position to where you want the creature to be spawned. It will spawn in a direction you are looking at. Don't look into the ground near you, or it will spawn there.
"spawn-Y-offset" and "Z-offset" you will leave at 0.
And for a level, you choose a desired level of the creature.
Here's an example if you want to summon level 100 Baryonyx, 400 units away from you
admincheat SpawnDino "Blueprint'/Game/PrimalEarth/Dinos/Baryonyx/Baryonyx_Character_BP.Baryonyx_Character_BP'" 400 0 0 100
