Research Abstract

Metabolic characteristics of fossilized extinct trilobite arthropods were quantitatively reconstructed. The exoskeletal area focused on was: doublural volume functioned as pericardium; inner pleural area functioned as the area for respiration; estimated axial volume stated as the place to demand the energy obtained in the respiratory area. Allometric changes (growth rates) of the former two against the last were documented on every two species of three ecomorphotypes..The rate of documented allometric scaling exponents appeared as highest in the case of illaenimorph and lowest in olenimorph. The former case means that the animal is likely characterized by the adrenaline rush in imergence, and the latter by static mode of behaviour.
