Key Points:

  • Scientists analyzed bones from 17 T. rex specimens under polarized light, discovering additional growth rings that had been missed in earlier studies.
  • The study suggests T. rex spent much of its life at mid-body size, with growth rates influenced by factors like food availability and environmental conditions.
