Sure, the garden variety raccoon is pretty scary, but this year, hordes of raccoons with distemper, a disease that attacks the nervous system and causes the animals to rise on their hind feet, bare their teeth, and stagger around like zombies, were reported in both Ohio and New York City.
Plateosaurus was a bipedal herbivore with a small skull on a long, mobile neck, sharp but plump plant-crushing teeth, powerful hind limbs, short but muscular arms and grasping hands with large claws on three fingers, possibly used for defence and feeding.
Polysyndactly of fore limbs and hind limbs and abnormal tooth development are fully penetrant [18].
The 12ft-long creature was equipped with claws, razor sharp teeth and long hind legs.
The research involved monitoring a single female macaque over one day observing three types of behaviour: agonistic (threats, chases, slaps), submissive (screaming, grimacing, hind-quarter presentation) and affiliative (teeth chattering, embracing and grooming).
These types of ants have a specialized spike along their abdomen that they stroke with one of their hind legs, similar to dragging the teeth of a comb along the edge of a table.
These Late Triassic and Early Jurassic forms include Plateosaurus (Fig. 3b), which had a long neck and plant-eating teeth but walked on its hind legs, and Thecodontosaurus, which had a relatively short neck, walked on its hind legs, and had teeth indicating a more omnivorous diet.
Tapirs have primitive features, such as four hoofed toes in the forefoot and three in the hind, and they have rather simple molar teeth.
Females of Sycophaga are strongly differentiated and exhibit several apomorphies, such as a flattened and elongated head, a short fore tibiae bearing teeth, numerous spurs on the hind tibia and an absence of any sculpture on the mesosoma.
