Review # 1 was written on 2020-03-31 00:00:00 James Greenhow To the best of my knowledge, this is the pinnacle of dinosaur poetry.

Review # 2 was written on 2011-01-06 00:00:00 Andrew Whillans Hilarious, if slightly dark, poems about various species of dinosaurs. Includes pronunciation tips and no evolutionary "facts". Winner in our house!
