Sorry, I'll try and answer the OP in a serious, sober fashion.
According to what I've read at JWN whilst lurking the WTS believes the dinosaurs were created by God to:
1. act as kind of earth-moving equipment and fertilise the soil;
2. provide coal as fuel for humankind (even though my lead lecturer's field of study is the microphytobenthos of lakes and esturies - she maintains that what is put into cars is largely the result of dead diatoms).
The above 'reasons' seem to work with dinosaur genera such as Diplodocus, Brachiosaurus, Triceratops and Stegosaurus (all herbivores that no doubt produced huge amounts of faeces - cf. cows, horses, elephants) but don't take into account smaller, carnivorous genera such as Velociraptor, Coelophysis, Troodon, Ornitholestes, or the two clades of pterosaurs represented by Dimorphodon and Pteranodon.
