Emva kokuqhekeka komhlaba kweendawo ezimbini zokuzonwabisa ezingaselunxwemeni zase-Oceanside ziphawule isiganeko seshishini lokhenketho lwedolophu yase-California. Le projekthi lolona phuhliso lukhulu lwaselunxwemeni kunxweme lwaseSan Diego ngaphezulu kweminyaka engama-20 kwaye iyaqhubeka nokuphakamisa iprofayili yase-Oceanside njengenye yeendawo ezishushu ezishushu nezisiza kubakhenkethi kwiSan Diego County. Ukutsala okungalindelekanga kwezokhenketho kuye kwaba yinto enkulu xa i-120,000 yeminyaka ubudala ithambo elivela kumnenga wokuqala wavela kwindawo yolwakhiwo i-Oceanside Beach Resort, waqinisekisa ubungqina bezinto zakudala.
Ubambo oluziinyawo ezine lubonakala ngathi luvela kwisidumbu esiye sahlamba elunxwemeni saza saqhekeka ngasekupheleni kwePleistocene Epoch xa inqanaba lolwandle laliphezulu kwaye unxweme lwalungaphezulu elizweni.
Abasebenzi babekwelona nqanaba lisezantsi lokumba kwabo xa kwavela ithambo. Babe malunga ne-25 okanye i-30 yeenyawo ubunzulu kumgangatho wento eya kuba kwinqanaba elisezantsi kwigaraji yokupaka ephantsi komhlaba, besebenzisa i-backhoe ukumba imingxunya yesiseko. Umthetho kaRhulumente ufuna indawo ezinkulu zokwakha ukuba nomcebisi kwindawo ukuze abukele naziphi na izinto ezinomdla ezinokuthi zivele ngexesha lokumba. Ikwafuna ukumba kuyeke, ngokufutshane, ukuze kufunyanwe nantoni na efumanekayo.
Sekunjalo, ithambo elinye lomnenga linceda ekwenzeni umfanekiso omkhulu wendawo owawukuyo lo mmandla kudala. Ifosili ekugqibeleni iya kusiwa kwiMyuziyam yaseSan Diego yezeNdalo kwiBalboa Park.
Ezinye iifosili ezibalulekileyo ziye zavela kwiindawo zokwakha zaseNorth County kule minyaka idlulileyo.
Ummandla waseSan Diego uphethe iifosili ezibhala ixesha elininzi kwimbali yoMhlaba.
I-Siltstone ilele iminyaka eyi-40 yezigidi ukuya kwi-50 yeminyaka ubudala eCarlsbad inamathambo agcinwe kakuhle eempuku zakuqala, iihele, ii-primates, ii-tapir, i-brontotheres kunye neenkamela. Kwakhona, ezinye zeefosili zedinosaur ezakhe zafunyanwa eCarlifonia zaziseCarlsbad, ukusuka kwixesha leCretacious ngaphezulu kweminyaka engama-70 ezigidi eyadlulayo. Kutshanje, mammoths baphila kulo lonke elaseNyakatho Melika kwaye baphela malunga neminyaka engama-4,000 XNUMX eyadlulayo. Amathambo abo afunyenwe kwiindawo ezininzi zokwakha kwi-county.
Nangona i-whalebone efumaneka e-Oceanside yayineminyaka engama-120,000 ubudala, mhlawumbi yayifana neleviathans ezininzi eziphila namhlanje.
