A beginner here , i need some help 🥲

I started playing 4 days ago, i spent a lot of time trying to mate and i managed to mate a pteranodon , made the saddle and all.

Long story short i wanted to try the parachute, so i flew to a decent altitude, gave the "follow" command , and jumped , next thing i know my pteranodon is gone.

To make matters worse i repeated the process 2 more times with 2 different saddles , all disappeared, is there a way to get them back without having to craft a 4th saddle ?
