Reptile

'''This small reptile was one of the first reptiles to ever exist and develop a blueprint that was required for us humans at a later point in time and that was a fast complex pumping heart to allow to outrun any invertebrates or amphibians that would see it as prey. Petrolacosaurus would have acted how most lizards would act like today basking in the sunlight, feeding on small enough insects and living in small holes too small for most monster sized bugs to be able to infiltrate. This small lizard would have also had speed and stamina on its side as another source of protection from the monsterous predatory bugs that roamed around the swampy environment it would have lived in, though they may have lived in the lowest layers of the underbrush as another source of safety against the bugs.'''

'''It may have had camouflaging colors on it as another source of protection against the bugs if it ever decide to go to the upper levels of the swampland canopy to go look for food elsewhere. Just like other lizards they may have laid their eggs in small burrows placed in soil and leave them be but, only after the temperature was properly regulated so that hatch-lings would be born more easily without getting too warm or too cold otherwise they would die.
