A groundbreaking discovery in southern China has unveiled the fossilized skull of a previously unknown species of sauropodomorph—a distant relative of the iconic sauropods like Brontosaurus and Diplodocus. According to Live Science, measuring up to an estimated 33 feet in length, this massive dinosaur lived around 200 million years ago, offering fresh insights into the early evolution of these giant herbivores.
A Dinosaur Unearthed from the Depths of Time
The fossil was found in 2007 in Yunnan Province’s Lufeng Dinosaur National Geopark, a region renowned for its wealth of dinosaur remains. Named Lishulong wangi, this specimen is believed to be the largest non-sauropod sauropodomorph discovered in the Lufeng Formation. These sediments, dating to the Early Jurassic Hettangian Age, are a treasure trove for paleontologists, having already yielded fossils of seven other early sauropodomorph species.
According to study lead author Qian-Nan Zhang, a paleontologist at the Chinese Academy of Sciences, the region’s unique sedimentary environment played a crucial role in preserving these ancient creatures. “The fine clays and silts deposited by prehistoric lakes and rivers protected the remains from erosion, while minerals infiltrated the bones, aiding fossilization,” Zhang explained.
Despite some compression over millions of years, the skull remains remarkably intact, with minimal bone loss—an extraordinary find for this group of dinosaurs.
What Makes Lishulong wangi Unique?
While most herbivorous dinosaurs of its time were medium to large, L. wangi stood out due to its size and anatomical features. Unlike its slow-moving sauropod successors, this dinosaur may have had the ability to walk on two legs. Zhang suggests it shared some traits with its close relative, Yunnanosaurus, which could alternate between bipedal and quadrupedal locomotion.
The researchers distinguished L. wangi from other species partly by its large nasal openings, an adaptation possibly linked to its environment or diet. Speaking of diet, Zhang hypothesized that this dinosaur likely fed on primitive plants such as ferns, cycads, and conifers, which dominated the lush Jurassic landscape.
A Glimpse into Its Life and Death
Analysis of the fossil indicates that L. wangi was an adult when it died, based on the fusion of certain skeletal elements. However, how it met its end remains a mystery. The partial preservation of its skull and neck vertebrae suggests that the remains may have been transported after death, making it difficult to determine the exact cause.
This discovery adds another piece to the puzzle of sauropodomorph evolution, offering valuable insights into the transition from smaller, more agile ancestors to the enormous sauropods that dominated later periods.
