Stupidity: Once Owen and Kayla have left the crashed plane, Kayla hands Owen a tracking device. She reveals that the ejector seat was installed with a beacon, and that the device is used to track the beacon. However, Kayla mentioned earlier that she only ever intended to use the ejector seat for herself, so there was no real reason for her to have installed the ejector seat with a beacon, unless she planned on tracking herself.
Stupidity: When the plane begins crashing, Kayla tells Claire that she is sitting in an ejector seat. She also mentions that there are no parachutes because she "wasn't expecting company." If Kayla was expecting to be alone in a crash scenario, what use would installing the ejector seat in one of the passenger seats have been? She would have to move from the pilot seat to the passenger seat while the plan is crashing. Surely it would've been easier to install the ejector seat in the pilot seat.
Answer: The live dinosaurs are genetically tweaked recreations, they're not the "pure" dinosaurs of the past, which would still be of great interest. Plus just like any other archaeology or historical study, there's always more to be learned about the past, and a great many people are interested in what the past has to teach us.
