I haven't been on the forum much over the last several years but I thought I'd share an article about a specimen I discovered in Montana in 2016; our KU Juvenile Tyrannosaurid. I was also hired as an assistant preparator at the KU Natural History Museum and I have been working on the specimen for several months. There is more material to the specimen than is shown in the video but we hope to share more as we move forward on our publication.

We are very proud of our KU fossil and it will hopefully answer several of the questions surrounding the Nannotyrannus debate
