Shark sitima zapamadzi. Kaya moyo chachinsinsi chilombo - Megalodon?

Ambiri asayansi-ichthyologists amakhulupirira kuti m'khutu woyera nsombazi amatchedwa "Megalodon" yaitali zinatha. Komabe, pali maganizo ndi mfundo zimene zimasonyeza kuti nsombazi sitima zapamadzi (dzina lakuti kuperekedwa kwa subspecies izi kwa nsombazo woyera) akukhalabe penapake mu kuya kwa kuya nyanja kuti ali kuwerengedwa anthu. Tiyeni tiyese kumvetsetsa funso limeneri lagona pa mbiri ya sayansi, iwo anapeza ndiponso mfundo.

History David George m'malo

David Dzhordzh Sted anali mmodzi wa asayansi ambiri otchuka komanso olemekezedwa m'munda wa ichthyology. Zinali nkhani yake, yomwe inafalitsidwa pambuyo pa imfa yake, anali ndi kutengeka ndi kuloledwa amakayikira woyera nsombazi sitima zapamadzi kulibe.

Mu 1918, wasayansi achinyamata ntchito ku Australia ndipo anali ndi udindo nsomba malonda mphepete South. Panthawi imeneyi mwa madoko akuluakulu m'chigawo bungwe udindo nsomba, kalata ifika kuti amafuna kuyendera bwino nkhani yovuta. Asodzi ananena kuti gombe la Australia pafupi cholengedwa mwachizolowezi choipa yosadziwika chinsomba, amene ali ponseponse, kuti iwo ali ndi mantha kupita ku nyanja.

msonkhano waukuluwo

Pa gombe akumuyembekezera yowawitsa nkhani ... Asodzi pa bwato m'nyanja kupita pamalo pamene iwo anali ozikika mu kuya kwa khwekhwe nkhanu za mtundu. Kosiyanasiyana ukutsika mu kuya, kuti unhook chingwe misampha, anapita capamwamba ndi liwiro zosaneneka. Mwamsanga scrambled kuti sitimayo iwo inanena kuti mu kuya kwa Nsombayo yaikulu. Kosiyanasiyana anauzidwa kuti nsombazi mosavuta chosakanikirana msampha nsomba akutiakuti. Koma iwo anali wotetezedwa ndi zingwe chitsulo! Ndipo iye sanamve kuwawa. Mwadzidzidzi, nsombazi anaonekera pamaso ndi otsala a gulu nsomba. Ndikuiwala za nsomba, iwo mwamsanga anayamba injini ndipo anasiya malo zoopsa.

Kumene, monga wasayansi, David Dzhordzh Sted ankadziwa kuti nsombazi ndi kutalika thupi la mamita oposa makumi atatu akhoza kukhalapo. Koma bodza mantha asodzi sizikanakhala zomveka. Pitani onani, kupeza wina umboni sanayese n'komwe. Asodzi ndinakanitsitsa kupita ku nyanja.

Sitimayo "Rachel Cohen '

A zaka zochepa nsombazi sitima zapamadzi (monga icho chinali kutchedwa asodzi kwa ndalama zosaneneka) anakumbukira nokha kachiwiri. Mu 1954, kachiwiri pa gombe la Australia, kuti akakonze ndi "kasupe kuyeretsa" anasiya ku doko la ngalawa "Rachel Cohen." Pamene chombo lidzayeretsedwa ndi zipolopolo zambiri, tinapeza seventini mano kwambiri. Aliyense dzino pa malonjezo a mboni, anali masentimita lalikulu kuposa eyiti. Asayansi apeza kuti aliyense koma nsombazi Megalodon, iwo sakanakhoza mwini. Pakuyenerera: dzino kutalika alipidwa woyera nsombazi ndizo itatu yokha asanu masentimita.

zolengedwa choipa chikhalire asanalengedwe

Malinga ndi asayansi, woyera nsombazi sitima zapamadzi ndi oyipa kwambiri, kukhetsa mwazi ndiponso zoopsa ana a amayi Nature. Akuti m'litali ndi pakati pa mamita makumi awiri ndi makumi asanu ndi manambala kulemera kuyambira fifite matani zana. Anangumi, chimodzi cha anthu lofunika kwambiri la nyanja - ndi kuwala akamwe zoziziritsa kukhosi kwa Megalodon. N'zovuta kulingalira mmene kukula nsagwada za Nsombayo sitima zapamadzi, ngati khumi mita yaitali chinsomba - mosavuta chakudya tsiku.

mano akulu, asayansi apeza padziko lonse lapansi akhala kwa zaka zambiri. Uwu ndi umboni wina wa chakuti woyera nsombazi sitima zapamadzi alipo ndipo (nacho) ndi zosaneneka Kupititsa kuthetsa kukula.

Ngakhale wowopsa kuyerekeza chilombo ngati kukula yaikulu, poyerekeza ndi zomwe munthu - monga kambewu ka mchenga. Shark sitima zapamadzi chithunzi chimene asayansi kulengedwanso chifukwa cha atulukira ndi ziphunzitso, ali wolengedwa kwambiri yonyansa. Iwo ali lalikulu-boned mafupa, zibwano chachikulu, chimene chili mizere asanu mano ndi yosamveka "ikhale pamphuno." Iwo ngakhale nthabwala kuti Megalodon zikuwoneka ngati nkhumba. Involuntarily anayamba kukondwera kuti zolengedwa anakhala zinatha.

Ndipo ngati zinatha?

Asayansi ndi akatswiri a nthaka kuzindikira nyama zinatha kokha pamene iwo tiribe za "uthenga" wa zaka 400 zikwi. Komabe, nkhani za asodzi ochokera ku doko ku Australia anapeza pa 'Rachel Cohen sitima mano - zonse izi zikuchitikadi chakuti pali Nsombayo sitima zapamadzi. mano anali pansi maphunziro ambiri, ndipo zotsatira zake zinali motere - iwo a Megalodon.

Ndipo anapeza "mano" chimphona amkunkhuniza ngakhale kwenikweni mantha. Iwo ali mphamvu ya zaka khumi kapena khumi zikwi. Kumvetsa kusiyana pakati pa zaka 400 zikwi ndi 11 zikwi! Iwo likukhalira kuti penapake mu kuya kwa nyanja likadali pamenepo ndi kumva woyera nsombazi sitima zapamadzi. Kuli akupezeka zambiri. Ndipo ichi ndi chinachake iye akuti inde.

Mwa njira, mwachitsanzo, goblin nsombazi, limene kwa zaka zambiri ankaona kuti zinatha, anatulukira mu 1897 ku nyanja. A nsombazi chinsomba, amene kulibe bola ankakhulupirira zapelengovana mu 1828. Mwina, nsombazi sitima zapamadzi kwinakwake kuyembekezera mapiko.

Ndingachitirenji osati zindikirani iwo?

Zingatanthauze kuti kukula yaikulu nyama sitingapeze analekerera kwa zaka zambiri. chilengedwe chachikulu ayenera kuti adawonekera kwa gombe, mu osaya, kapena kumbuyo kwa ngalawayo. Koma ngati mukuganiza, miyeso chidwi cha zimphona izi chabe sanawalole kusambira pafupi pagombe. Ndi chochepa kwa iwo.

Komanso, nsombazi sitima zapamadzi mosavuta kukhalapo mu kuya kwa nyanja. Mwachitsanzo, nyama yaikulu - zinsomba umuna - bwinobwino moyo pa akuya makilomita atatu. Munthu pansi ngati pali simungathe ngakhale chitukuko cha sitima zankhondo ano. Chotero kuya kwa ife chabe palibe panobe. Ndipo ngati mukuziyenereza kukula kwa zinsomba umuna ndi nsombazo, sitima zankhondo, yotsirizira bwino Umapeza. Choncho akuya kumiza kungakhale kuposa "wodzichepetsa" makilomita atatu.
