The animal that only has teeth on the bottom is the Giraffe.
Giraffes are the only animal that has only bottom teeth and no top teeth.
Although giraffes have 32 teeth like humans they only have bottom teeth and no top teeth.
Giraffes also have a thick, dense tissue layer that is called a dental pad in place of their top teeth.
Giraffes eat 70 lbs of food a day so the bottom teeth get a good workout.
A giraffe does not need top teeth or front teeth to eat because they use their teeth to comb leaves off of branches.
The giraffe is a large African hoofed mammal belonging to the genus Giraffa. It is the tallest living terrestrial animal and the largest ruminant on Earth.
Traditionally, giraffes have been thought of as one species,
Giraffa camelopardalis, with nine subspecies.
Though giraffes as a species are not considered endangered, some giraffe subspecies are.
Out of eight assessed subspecies, two—the reticulated giraffe and the Masai giraffe—are classified as endangered.
Another two, the Kordofan giraffe and the Nubian giraffe, are critically endangered.
Meng, both the creature's teeth and inner ear structure were reminiscent of modern giraffes.
They determined that Discokeryx was one of the earliest graffids, an ancestral group of hoofed mammals that gave rise to giraffes.
Discokeryx likely resembled an okapi, a forest-dwelling cousin of modern giraffes.
