It has eggs like Wyvern and Rock Drakes. All you need to do is find the eggs. The only thing I know location wise is somewhere in a lava cave there is a tunnel with purple crystal on the walls and ceiling. When you go through that tunnel there is a large room with a lava lake in it. There will be lots of Magmasaurs in the room guarding the eggs. Note that the eggs are on the surface of the lava, so you might want to use a flying Dino and a grappling hook.

I have stolen many

of these eggs from volcano.unfortunately my way requires a bloodstalker.

Get up on the ceiling above the egg u want web straight to it dismount,yoink the egg jump back on and web straight away DO NOT JUMP STRAIGHT UPWARD,u will die if u do.only web out. Sidenote magma burning bloodstalker feet doesn't prevent webbing only having the torso on fire does

for fjordur: use a desmodus and sneak into the fire wyvern trench at night. at the end of the trench is an amethyst cave; keep going all the way back until you hit a big cave full of magmasaurs. use a spyglass to check out the eggs. land next to one, grab it, hop back on, and get out FAST. other hazards besides the magmasaurs include rock elementals, onyc, scorpions, and centipedes.

Pick up any Lvl maewing and increase its stamina to 1000, fly down into the amethyst cave on Genesis, stick to the farthest wall when you land. Spot your egg, walk through or around the lava with your Maewing, grab the egg and then gtfo using your mount. With enough stamina you'll be able to get out before the magmas aggro onto you. Get somewhere safe and teleport away.
