Randomly choose a letter from each of the six words: last letter, 4th letter, 7th letter, 8th letter, 8th letter, 4th letter
Once I have chosen those letters, I need to unscramble them to make the name of a carnivorous species of dinosaur.
One of the fourth letters is definitely "h" from archaeopteryx.
