Description
I nearly forget this matter. Spinolurus show a very interesting allometric pattern. Adults are fully quadropedal (they stand only on their hind limbs to reach higher branches or bird nests). Juveniles and babys are instead bipedal until they reached a lenght of 3 meters (between 3 and 4 years old). The bigger/older specimens are called Burrunjor and were once descriped as a seperate species.
Another difference to flying dragons is the state of parental care and the number of eggs. Spinolurus often laying up to ten eggs (Eurovenator only 2) and between 6 and 8 chicks are normal. Babys following their parents during the first weeks but these don't looking much aftern them. With an age of 7 weeks (this state is shown here) they leave the adult animals. During this time they are active at night and day to cover their food needs, their diet is a bit more meat-heavy. During the first two years they often live together to warn each other because of predators (they stay in contect with their long tails). Many juveniles become killed during their first year by snakes, wedge tailed eagles, dingos and dieseases/parasites but mainly the perentie and the lace monitor. Often only one of ten reach the adulthood.
