Ua ʻike ʻia nā ala ala he nui me 200 mau kapuaʻi dinosaur ma kahi papahele ʻili ma Oxfordshire. ʻO kēia mau lā i ka Middle Jurassic Period (ma kahi o 166 miliona mau makahiki aku nei). ʻElima mau alahele i hana ʻia e nā sauropods herbivore. He mea koʻikoʻi kēia no ka mea he kakaikahi nā wahi track sauropods. Eia kekahi, pili nā ʻike hou i nā alahele dinosaur i ʻike ʻia ma ia wahi i ka makahiki 1997. Ua kākau ka hui noiʻi i nā kapuaʻi wāwae hou i nā kikoʻī i ʻike ʻole ʻia a kūkulu i nā hiʻohiʻona 3D kikoʻī o ka pūnaewele no nā noiʻi ʻana i ka ʻepekema dinosaur no ka hoʻomālamalama ʻana i ka hoʻoilina o ka Honua.
Ua hoʻomaka ʻia me ka mea hana e hoʻāʻo nei e wehe i ka pālolo e hōʻike i ka papahele ʻili ma Dewars Farm Quarry ma Oxfordshire i ka wā i manaʻo ʻia ai nā 'puʻu maʻamau'. Ua kāhea ʻia nā poʻe loea e noiʻi ʻoiai ʻo ka ʻeli ʻana i ka limestone ma ia wahi i alakaʻi ʻia i ka loaʻa ʻana o nā alahele dinosaur me kahi o 40 sets o nā kapuaʻi.
Ua mālama ʻia ka ʻeli ʻana o ka pūnaewele i ka mahina ʻo Iune 2024 ma kahi o 200 mau kapuaʻi dinosaur like ʻole i kanu ʻia ma lalo o ka lepo no ka Middle Jurassic Period (ma kahi o 166 miliona mau makahiki).
ʻElima mau ala ala nui. ʻO ke ala hoʻomau lōʻihi loa ma kahi o 150 mika ka lōʻihi. ʻEhā o nā ala ala i hana ʻia e Sauropods a ʻo ka lima i hana ʻia e ka Megalosaurus. He mea koʻikoʻi ka loaʻa ʻana o ʻehā mau ala hele Sauropod no ka mea he kakaikahi nā ala Sauropod.
Hiki i ka herbivore Sauropods a me ka carnivore Megalosaurus ke hele i kekahi wahi o ka pūnaewele e hōʻike ana i ka pilina ma waena o lāua. ʻO nā Sauropods he mau dinosaur nui, ʻāʻī lōʻihi, herbivorous. ʻO Megalosaurus, ma ka ʻaoʻao ʻē aʻe, he dinosaur theropod carnivorous me nā wāwae ʻokoʻa, nui, ʻekolu manamana me nā maiuu.
Hoʻopili nā ala ala hou i ʻike ʻia i nā wāwae dinosaur i ʻike ʻia ma ka wahi like ma mua o 1997 i hāʻawi i ka ʻike e pili ana i nā dinosaur e noho ana ma ia wahi i ka wā o ka Middle Jurassic Period. Eia nō naʻe, ʻaʻole hiki ke loaʻa ka pūnaewele kahiko no ka noiʻi hou. He mea nui kēia no ka noiʻi ʻana i nā ala ala hou.
Me nā kiʻi 20,000 a me nā hiʻohiʻona 3D kikoʻī e hoʻohana ana i ke kiʻi drone lewa, ua kākau ʻia ka pūnaewele i ʻike ʻia ma kahi kikoʻī i ʻike ʻole ʻia e ka hui noiʻi. ʻO nā haʻawina e hiki mai ana i ka ʻepekema dinosaur no ka hoʻomālamalama ʻana i ka hoʻoilina o ka Honua o ia wā pono e pōmaikaʻi mai kēia mau kumuwaiwai.
Aia kahi moʻolelo o ka ʻike ʻana i nā ala dinosaur ma UK. Ua ʻike ʻia ka pūnaewele ma Spyway Quarry ma Dorset, hema ʻEnelani i ka hopena o nā makahiki 1990 kahi i ʻike ʻia ai ma mua o 130 mau mele pākahi o nā sauropods nui.
Ua hoʻopau ʻia nā dinosaur mai ka honua aku ma kahi o 65 miliona mau makahiki i hala i ka wā Cretaceous i ka wā ʻelima. make ma muli o ka hopena asteroid.

. The are five trackways of which four were made by the herbivore Sauropods. This is significant because Sauropods track sites are comparatively rare. Further, the new findings connect to the dinosaur trackways discovered in the same area in 1997. The research team has documented the new footprints in unprecedented detail and built detailed 3D models of the site for future study in dinosaur science for shedding light on Earth’s heritage.){kind=link}
