Nicely done!
No evidence of cropping that I can see . . ..
But here's my far out theory. It will sound like B.S. but nonetheless it may be possible to inquiring minds with a lot of time on their hands and nothing to do.
You had the camera on a stand. You took two pictures. You set the camera to a timed exposure so you could jump behind the bike and throw that terradactyl just high enough to be in the proximity of the scoot but higher than your head.
Then you got behind the camera and took another pic just of the scoot. It was done so quickly that the clouds in the background hardly moved.
And finally you took the pic of just the scoot and then copy and pasted the upper half of the terradactyl shot into the frame and blended the border between both pics to make it look seamless.
Oh. . .and there was somebody else who followed you there with dino bird in a car so you didn't have to carry it and could ride safely.
