What was the lower estimated length provided for *Xenotarsosaurus* in the size comparison table?
Answer
5.4 meters (18 ft)
Determining the definitive size of *Xenotarsosaurus* is difficult due to relying on partial remains, necessitating reliance on comparisons with more complete dinosaurs. The provided data presents estimations from different years. The lower estimate for its length, cited in figures from around 2016, puts the dinosaur at 5.4 meters, which is equivalent to 18 feet. This figure contrasts with the higher estimate of 6 meters (19.7 ft) derived from earlier data, illustrating the margin of uncertainty inherent in extrapolating whole-body size from just a femur and vertebrae.
