演講摘要: 已知最早的恐龍胚胎與其演化含義

The Golden Gate Highlands National Park in South Africa and the area around it are well known for the many articulated skeletons of the 190 million year old dinosaur Massospondylus, a prosauropod dinosaur, and part of a clade of early dinosaurs that gained a worldwide distribution in the Late Triassic and Early Jurassic. The skeletons of this herbivorous dinosaur range in size small juveniles to full adults. This presentation will show how we found the eggs and embryos of this early dinosaur in a road cut in that park. You will also find out how an international team led by Professor Robert Reisz studied these tiny embryos, their nests, and the various juveniles and adults, and were able to learn about the reproductive behavior of this early dinosaur, and how it managed to grow from a 18 cm quadrupedal hatchling to a 5 m bipedal adult.

南非金門高地國家公園與其附近，出土了很多有名的1.9億年前大椎龍鉸接骨骸，牠是原蜥腳類恐龍、在晚三疊紀早侏羅紀期間、分佈全球的早期恐龍分支，這種植食性恐龍的骨骸，從小幼體到成龍都有。這份報告將說明我們如何在公園內一處開路露頭發現恐龍蛋和胚胎，也會說明瑞茲教授如何率領國際團隊研究這些細小的胚胎、蛋窩、和好些幼龍與成龍，我們從此得知這些早期恐龍的繁殖行為，並如何從18公分四足剛孵出的幼龍成長到5公尺二足的成龍。
 
Professor Robert Reisz is a vertebrate paleontologist at the University of Toronto, chair of the Department of Biology, UTM, and research associate at numerous museums. His research has focused on major events in the evolutionary history of vertebrates, and includes studies on the evolution of teeth in early fishes, the initial diversification of vertebrates on land, the origin of turtles, the origin and early history of herbivory in terrestrial vertebrates, and the initial stages of dinosaur evolution. His dinosaur work focuses on the South African Massospondylus and its relatives.
瑞茲教授是一位脊椎動物古生物學家，多倫多大學生物系主任與諸多博物館的研究夥伴，他的研究著重於脊椎動物演化史中的重要事件，包括早期魚類牙齒演化的研究、陸地脊椎動物起始與多樣化、烏龜起源、陸地植食性脊椎動物的起源和早期歷史、以及早期恐龍演化，他的恐龍研究聚焦於南非大椎龍和相關的項目。
