Syst. VL - 3 IS - 1 SE - Original research DO - 10.37819/biosis.003.01.0168 UR - https://eaapublishing.org/journals/index.php/biosis/article/view/168 SP - e003 AB - <p>An isolated but moderately well-preserved theropod track from the coal-bearing strata of the Zhangjiakou City region of Hebei Province was reported to have originated from the Xiahuayuan Formation, which is considered Middle Jurassic in age. Although the track has a wide divarication angle and length-width ratio reminiscent of Cretaceous tracks like <em>Magnoavipes</em>, it would be speculative to apply this Identification based on a single track. Therefore, it is considered most likely to be a preservational variant of <em>Kayentapus</em>, in which the heel trace is lacking. <em>Kayentapus</em> is widely known from the Lower Jurassic of China. This is the first report of a track or any vertebrate fossil from the Middle Jurassic of this region of Hebei Province, China.</p> ER -
