Troodon was a theropod dinosaur from the Late Cretaceous.
It is possible that Troodon is the raptor in the series, because in Extinction Event they are described being similar to the Raptors at the Shopping Mall. This does not mean they are Troodon, it's just a slight possibility. However, the Raptors in the series are confirmed to be Dromaeosaurus, and therefore, the possibility is slim to none.
Cutter, Connor, Abby and other Russian soldiers witness some Troodon in the forest. Later, Tim Jenkins, who was badly injured by Dimetrodon in the Permian is attacked and killed by a pack of Troodon. Even later, some Troodon appear after an Ankylosaurus knocks over Jenny's car, and are scared off by Jenny.
