My favourite of all dinosaurs has always been a Brontosaurus. This could be due to my love of Littlefoot in the Land Before Time, mainly due to how adorable he is and how he is a strong little dino that seems to get through all his struggles.
Brontosaurus dinosaurs may not have been exactly like Littlefoot, his mother or his grandparents, but this is the reason I adore them so much. Another plus side is that these dino's are veggie's. There wouldn't have been any worry about being eaten around these lovely creatures. I just want to squish Littlefoot in a tight embrace, he's way too cute for his own good!
