Sue's Significance

The first T. rex specimen was found in 1900. Since then, only seven skeletons that are more than half complete have been discovered. Of these, Sue is the largest, most complete, and best preserved T. rex ever found.

Most of Sue’s bones are in excellent condition and have a high degree of surface detail. Sixty-seven million years after her death, it is still possible to see fine details showing where muscles, tendons, and other soft tissues rested against or attached to the bone.

Sue’s completeness, combined with the exquisite preservation of the bones, makes her an invaluable scientific resource, permitting highly detailed study of T. rex anatomy. (© The Field Museum GEO86166_3c)
