在遮天蔽日的松柏林深處，潮濕溫暖的空氣中迴盪著沉重的腳步聲。漫長的中生代荒野中，兩大以植物為主食的恐龍在不同的時代裡，展現出截然不同的生存智慧。
為了攝取足夠能量以維持龐大的防禦體型，生活在大約6800萬年前的三角龍，能用牙齒切斷最堅硬的針葉樹與蘇鐵纖維，而牠招牌的三角頭盾，不只有防禦功能，還能調節體溫散熱。
曾經，學者推論腕龍生活在水裡，用靠頭頂那個大孔洞像潛水管一樣呼吸。然而，當代生物物理學研究證實，如此龐大的身軀一但沈入水中，水壓會壓迫胸腔，無法靠吸氣撐起肺部，因此不能呼吸。而且，真正的鼻孔是長在靠近嘴巴的地方。腕龍其實是不折不扣的陸棲動物。以植物為主食的腕龍，能用牠的長脖子吃到其他恐龍吃不到的高處植物。
不論是擁有特別頭盾的三角龍，還是被現代科學重新探索的腕龍，都為我們完美演繹了在那個弱肉強食的恐龍時代，生命是如何為了生存，演化出驚人的適應力。
Deep in a pine and cypress wood that shuts out the sun, heavy footsteps roll through warm, damp air. Across the long Mesozoic wild, two great plant-eating dinosaurs, in different ages, showed utterly different wisdoms of survival.
To take in enough energy to keep a huge defensive body, Triceratops, living about sixty-eight million years ago, could cut the hardest conifer and cycad fiber with its teeth. Its famous three-horned frill was not only a defense; it could also shed heat and regulate temperature.
Scholars once inferred that Brachiosaurus lived in water, breathing through that large hole on the crown like a snorkel. Contemporary biophysics has shown that a body so huge, once sunk, would have the chest crushed by the pressure; it could not inflate the lungs by drawing air, and so could not breathe. And the true nostrils sit near the mouth. Brachiosaurus was a land animal through and through. As a plant-eater it could, with that long neck, reach the high browse other dinosaurs could not.
Whether the Triceratops with its special frill, or Brachiosaurus as modern science has looked at it again, both show us perfectly how, in that age of dinosaurs where the weak were meat, life evolved a startling power to adapt in order to live.
