Qhov sib txawv tseem ceeb ntawm ammonite thiab ammolite yog tias ammonite yog lub plhaub cephalopod uas tau ploj mus txog 66 lab xyoo dhau los, thaum ammolite yog opal zoo li cov organic gemstone.
Ammonites yog cov kab mob uas ploj mus pom raws li pob txha. Ntawm qhov tod tes, ammolite yog lub pov haum uas los ntawm ammonites. Yog tias cov pob txha muaj nyob hauv lub plhaub glossy, nws tseem hu ua ammonite fossil. Thaum tsis muaj pob txha, nws hu ua ammolite. Ntxiv mus, ib qho ammonite yuav tsum tau faus tob hauv qab hiav txwv yam tsis muaj oxygen thiab cua sov kom dhau los ua lub pov haum ammolite.
Ammonite yog dab tsi?
Ammonite yog lub plhaub cephalopod uas tau tuag txog 66 lab xyoo dhau los. Fossils ntawm ammonites muaj nyob thoob plaws lub ntiaj teb no, tej zaum nyob rau hauv loj heev concentration. Ammonites yog ib pawg ntawm cov tsiaj txhu uas ploj lawm nyob rau hauv sub-chav kawm ntawm Ammonoidea ntawm chav kawm Cephalopoda. Cov chav kawm Cephalopoda tau muab faib ua peb pawg, suav nrog coleoids, nautiloids, thiab ammonites. Cov tsiaj ntxov tshaj plaws ntawm ammonites tshwm sim thaum lub sijhawm Devonian geology, thiab cov tsiaj kawg tau ploj mus nyob rau hauv Creataceous-Paleogene extinction tshwm sim los yog thaum lub sij hawm Danian epoch ntawm Plaleocene geological lub sij hawm. Ammonites yog qhov zoo tshaj plaws index fossils. Lawv cov pob txha pob txha feem ntau siv daim ntawv ntawm planispirals. Txawm li cas los xij, cov ntawv helically spiraled thiab non-spiralled forms kuj tau pom.
Daim duab 01: Ammonite
Ammonites tau txais lawv lub npe menyuam yaus nab pob zeb vim lawv cov qauv thiab cov duab, txawm tias lawv tsis yog tsiaj reptiles. Cov Ammonites tau yug los nrog cov plhaub me me, thiab thaum lawv loj tuaj, lawv tau tsim cov chav tshiab rau lub plhaub. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg. Ib txhia ntawm lawv tsuas yog ob peb millimeters, thiab lwm tus yog loj loj. Cov ammonite loj dua tau tshwm sim los ntawm lub sijhawm Jurassic lig dhau mus. Ntxiv mus, ntau ammonites tej zaum nyob rau hauv qhib dej ntawm ancient seas. Tsis tas li ntawd, hom ammonite loj dua yuav tau noj crustaceans, bivalves, thiab ntses, thaum cov tsiaj me yuav tau noj plankton.
Ammolite yog dab tsi?
Ammolite yog ib lub pob zeb zoo li opal zoo li ib txwm pom nyob rau sab hnub tuaj ntawm Rocky Toj siab ntawm North America. Nws yog ib txwm ua los ntawm fossilized plhaub ntawm ammonites. Ammolites yog tsim los ntawm cov ntxhia hu ua aragonite, tib yam ntxhia muaj nyob hauv nacre (niam pearl). Nws yog ib qho ntawm ob peb biogenic gemstones. Lwm cov gemstones biogenic muaj xws li amber thiab pearl.
Daim duab 02: Ammolite
Nyob rau xyoo 1981, ammolite tau muab cov ntaub ntawv pov thawj los ntawm World Jewellery Confederation (CIBJO). Kev lag luam mining ntawm ammolites tau pib tib lub xyoo. Nws tau raug xaiv los ua lub pov haum tseem ceeb ntawm Lub Nroog Lethbridge, Alberta, xyoo 2007. Tsis tas li ntawd, Marcel Charbonneau thiab Mike Berisoff yog thawj tus tsim ob npaug ntawm ammonite lub pov haum xyoo 1967.
Dab tsi yog qhov zoo sib xws ntawm Ammonite thiab Ammolite?
- Txheej ntawm qee cov ammonites hloov vim muaj tshuaj lom neeg, yog li tsim ammolites gemstone.
- Ammolite yog lub npe lag luam rau txheej txheej nacreous ntawm lub plhaub ntawm cov pob txha ntawm ammonites.
- Ob leeg muaj qhov tseem ceeb rau cov kws tshawb fawb thiab cov tub luam.
- Ob leeg tuaj yeem pom nyob rau thaj tsam ciam teb ntawm Canadian Rocky Toj siab.
Qhov txawv ntawm Ammonite thiab Ammolite yog dab tsi?
Ammonite yog lub plhaub cephalopod uas tau ploj mus txog 66 lab xyoo dhau los, thaum ammolite yog opal zoo li cov pob zeb zoo li cov organic ib txwm pom nyob rau sab hnub tuaj ntawm Rocky Toj siab ntawm North America. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ammonite thiab ammolite.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm ammonite thiab ammolite hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Ammonite vs Ammolite
Ammonites yog cov kab mob uas ploj lawm uas pom muaj pob txha. Ammolite yog ib lub pov haum uas los ntawm ammonites. Ammonites yuav tsum tau faus tob hauv qab hiav txwv tsis muaj oxygen thiab cua sov kom dhau los ua ammolite organic gemstones. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ammonite thiab ammolite.
