在中国重庆綦江区虎山足迹点发现了2个大型恐龙天然足模化石,化石赋存于砂质富集的夹关组的一悬崖底面。它们属于罕见的幻迹,同类足迹也发现于韩国和北美白垩系足迹点。放射状、同心及半脆性形变使这些幻迹具有切断状或网状外观,有时呈现出类似裂断花或菜花的形态。这正是当地“石头开花”民间传说的来源。这些特征表明,造迹者必然是恐龙,同时也清晰地展现了其外形态学特征。
Two large dinosaur natural foot mold fossils were found at the foot of Hushan in Qijiang District, Chongqing, China. Fossils were found on the bottom of a cliff in the sand-rich clan group. They belong to a rare illusion, similar footprints are also found in South Korea and North America Cretaceous footprint. Radial, concentric, and semi-brittle deformations make these ghosts have a cut or reticular appearance, sometimes exhibiting a morphology that resembles split or cauliflower. This is the source of local “stone blossom” folklore. These characteristics show that the singer must be a dinosaur, but also clearly demonstrate its morphological characteristics.
