When you hunt a dinosaur, a ship (ranger helicopter) will retrieve the dead dinosaur (your trophy) and will take it to the trophy room, so you can go there and take a look at your hunted dino by selecting the "Trophies" option in main menu.
"The Secret Trophy Room"
This trophy room is a secret base located in an unknow place, nobody knows its location exactly. Each hunted dinosaur will be exposed there and when you step above a jurassic park logo carved on ground, the info about that hunted dino will be displayed (size, weight, date, range of kill, etc...).
The characteristic parts of the trophy room will be shown below :
