Good luck with what your doing... :)
In reptiles, fertilization usually takes place internally inside the female's body. Male reptiles deposit sperm inside the female through cloacal contact during copulation. The sperm then fertilizes the eggs within the female's reproductive tract.
internal fertilization
internal because they give eggs and so they have a internal fertilisation
Human evolution goes back from mammals (what we are) to reptiles. One of the huge breakthroughs in the sucess of reptiles was adapting to a land existence. This included both internal fertilization and the amniotic egg (prior to this (by and large) animals shed their gametes into the water.. Our fertilization is internal because via the processes of evolution and adaptation that shapes all life on this planet yielded internal fertilization as a way to live on land yet still be able to keep the gametes (sperm and egg) from drying out. Like your private parts...thank a reptile!
Reptiles and birds are among the major groups of vertebrates that have internal fertilization and external development. Also included are monotremes and marsupials.
Reptiles ONLY have internal fertilization
Dinosaurs were reptiles and like all reptiles, use internal fertilization.
Internal fertilization
All reptiles are internal
internal fertilization
Because.
Since most reptiles have hard shells, it would be impossible to fertilize an egg after it is laid. Therefore most reptiles perform a sort of internal fertilization.

Fertilization is exclusively internal in most mammals and some reptiles, such as birds and most viviparous (live-bearing) species. In these species, sperm fertilizes the egg inside the female's body, before the zygote develops and the offspring are born alive.

Birds, mammals and reptiles carry out internal fertilization. This is evidenced by the fact that the eggs are stored internally during fertilization. The egg develops inside of the mother.
