Sepia photograph of a T-Rex skeleton mounted upright so its tail rests on the floor. Two men one standing and one seated on the floor provide scale.

Apparently it was once thought that T. rex stood more upright than is believed now, with its tail on the floor. I believe this to be the fourth T. rex specimen unearthed - by Barnum Brown in 1908 - which was mounted for display in this manner. However, I have not been able to verify this belief of mine.
