@DavidBrown Clearly the T. rex has gotten itself stuck in quicksand. In all seriousness, according to the website of the people that made the dinosaurs, this is suppose to be a photo op opportunity (Tyrannosaurus Photo Op). However the fact that it's roped off from the path suggests that this zoo chose not to go that route.
Also two things:
1) I love the Jurassic Park inspired vehicle.
2) Note to be "that guy" but for future reference, it isn't T-rex, like t-shirt, it's T. rex because its a scientific name. You wouldn't say P-leo would you? You'd say P. leo. Makes sense? Once again note trying to be rude, just helpful.
