Blimey! What laid these?

Actually I had this picture on my PC in an old folder, I was looking through them and found this, I just had to post it.
But no doubt someone on here will know what bird laid them lol.

I think a Phoenix creature laid the smaller one.
The larger one.... could be a dragon.

That's not a bird, it's a dinosaur! Wait Actually...it's a pterosaur.
