4079 Mini Rex is a small Promotional Jurassic Park 3/Studios set released in 2001. It contains a Baby Tyrannosaurus Rex. This is very different from the other dinosaur parts because it was red instead of green. No other sets include it in this colour. It also contained a small platform and perch for the dinosaur.
- Strangely, because this is a LEGO Studios promotional set, it seems odd that the company (LEGO Studios [Not the real life company]) was able to capture a real dinosaur. It may be just a robot or a dummy.
- Also Strangely, this Mini T-Rex was released in red, the T-Rex before this, was released in green. The only reason for this might have been that LEGO was promoting Coca-Cola, because they were the ones giving this out.
