* Unfortunately, I can't quote reliable sources, but I remember that I read somewhere that lifeforms without a biological time-bomb tend to grow until the square-cube law kills them. This article [http://www.flmnh.ufl.edu/cnhc/cbd-faq-q2.htm Crocodilian Biology Database, at www.flmnh.ufl.edu] discusses this theory that alligators grow forever. The biological time-bomb is a '''good''' thing for the species, because it allows old and big speciments to leave and give space to the new generation.

:In order to observe that indefinite growth, we would need to find a lifeform without a "biological time-bomb". The only one I can think of is the [http://www.telegraph.co.uk/earth/wildlife/4357829/Immortal-jellyfish-swarming-across-the-world.html Turritopsis Nutricula] and it does not grow indefinitely. The article on crocodiles says that they "reach a maximum size where growth stops or becomes extremely slow in old age". We would also expect the presence of gigantic, fossil human skeletons. This brings to mind the theory that [http://www.angelfire.com/mi/dinosaurs/patriarch.html Neanderthal fossils are the remains of the first humans], whose facial bones would have grown for centuries.

::Most Jellyfish are short lived, but all of the sessile cnidarians are immortal, however they reproduce by budding and that helps them dodge the cube-square law. I'm still not sure I agree with your analysis of this study, however you may also want to look for a dinosaur expert who has been saying that as many as 1/3rd of the kinds of dinosaurs that we find are just juveniles and not new kinds. He has done extensive work looking at the structure of the growing bone and might have something you could use. --[[User:JimPT|JimPT]] 11:33, 8 April 2010 (EDT)
