Autonomic Nervous System Function in Extinct Giants


Clifford Qualls, Lucas S and Appenzeller O

We measured published growth-lines in bones of two titannosaurs from images in the papers. We found that growth-lines in osteons in the anterior process of the rib grew faster than dense bone and juveniles grew faster than adults Power spectral analyses of growth intervals in osteons showed a ratio of 1.3 (LF/HF) and for bone 1.4 (LF/HF) NS. We found additionally that the main drivers for blood flow to the brain were the physical aspect of flow in elastic tubes (blood vessels) and the smallness of their brains. These animals slept only ~3 hours/24 hours because of the need to sustain their enormous body mass (~80 tones) and they reached an age of ~100 years.
