It is possible that Tinker could have begun to hunt for himself but he was pretty young. Did Tinkers parents feed him? It would seem so. The baby teeth are needle sharp for snagging insects, frogs and other small prey. As an example of what this means today, baby crocodiles have totally different teeth than adult crocodiles. It would have been a meal identical to what his parents would have eaten. There were some acid eroded and etched duckbill remains mixed in with Tinkers bones, indicating his last meal. He must have eaten the same food as the adults. The fact that Tinker has the same teeth as an adult Trex plus the fact that there is no indication of Tinker having had different baby teeth tells us a lot. Tinker has those same teeth so is a Late Cretaceous T-rex and not something else. These crowns are taller relative to diameter and more circular in cross section than any other member of the tyrannosaurid family Tinkers lower jaws hold a single nipping tooth and 12-13 tooth sockets per side. Tinkers teeth have tall, conical, slightly recurved anterior crowns. Tinker is clearly a T-rex because of his teeth. In human years, Tinker could well have been a teenager. It is two thirds adult size and only one fourth adult weight. Tinker is the skeleton of a juvenile t-rex. Here, for the first time, is an opportunity to study the body build and athletic prowess of a juvenile rex and to investigate the way young rexes chewed their food Tinker is the first specimen that allows us to unlock secrets of the Trex Parent/child bond. Tinker is the very first most complete skeletons of a Trex youngster, an individual only one-fourth adult weight. Bakker stated the following: Tinker is one of the most scientifically significant and most exciting Trex skeletons ever found, and one of the most important dinosaur specimens from any age and any locale.
