It is impossible to think the Baby was the juvenile, Jurassic Park follows the years of the real world chrongically and the year span for a Tyrannosaurus to grow is up to 20 years. The baby T. rex still was too young up to the extent where it was depending on its parents to aid it and since the events of The Lost World took place in 1997 by the events of Jurassic /// in 2001 the baby would still be a young age and not fully grown as the one that fought the Spinosaurus. To support this more there aren't many predators to go by on Isla Sorna so by this reason along with the genetics of it's parents it might have taking the baby longer to grow.
