O QUE SIGNIFICA CONODONT EM INGLÊS
Conodont
Conodonts são cordados extintos que se parecem com enguias, classificados na classe Conodonta. Durante muitos anos, eles eram conhecidos apenas por microfósseis dentários, agora chamados de elementos de conodontes, encontrados isoladamente. O conhecimento sobre os tecidos moles permanece relativamente escasso. Os animais também são chamados Conodontophora para evitar a ambiguidade. Os dentes do conodont são os primeiros dentes que encontramos no registro fóssil. Neil Shubin escreve: "Durante muito tempo, os conodonts eram enigmas: os cientistas discordavam sobre se eram animais, vegetais ou minerais. Conodonts foram reivindicados como pedaços de amêijoas, esponjas, vertebrados e até worms. A especulação terminou quando os animais inteiros começaram a mostrar Os paleontologistas discutiram sobre por que os esqueletos rígidos, aqueles que contêm hidroxiapatita, surgiram em primeiro lugar. Para aqueles que acreditavam que os esqueletos começavam com a espinha dorsal ou a armadura corporal, os conodões fornecem um "dente inconveniente" se Vocês. As primeiras partes do corpo contendo hidroxiapatita foram dentes. Os ossos duros surgiram para não proteger os animais, mas para comê-los. "...
