To learn more about this giant supercroc , the two scientists turns to today s crocodilians 为了更了解这超级巨鳄，这两位科学家先著手于研究现今的鳄鱼。

Yet the animal that had once wielded these jaws was not a dinosaur . it was a colossal crocodilian 然而，曾经拥有这种下颚的动物不是恐龙，而是一种巨大的鳄鱼。

Habit of the chinese crocodilian lizard ( shinisaurus crocodilurus ) was observed in the field and laboratory from 2004 to 2005 摘要2004 ~ 2005年，通过野外调查和半自然条件下饲养的方法研究了鳄蜥的生活习性。

" there were forests in the arctic and antarctica , " added schrag , who is unaffiliated with the study . " there were crocodilians living on ellesmere island in the arctic . “南极和北极都是森林，北极圈内的埃尔斯米尔岛上生活着鳄鱼。 ”

The results indicated that chinese crocodilian lizards distributed in streams of mountain , and mainly lived in four types of vegetation : broadleaf forest , conifer and broadleaf mix - forest , shrubbery and bamboo forest 鳄蜥主要栖息于阔叶林、针阔混交林、灌木林荫、竹林4种植被类型的山冲溪沟之中。

Two captive populations could n ' t be defined as separate evolutionary significant units ( esus ) because of lacking of genetic divergence between them , and should be considered as a single esu in the conservation of the species . by comparing the sequences of control region of mitochondrial dna from three species of crocodiles , it is revealed that the smallest genetic diversity exists between alligator sinensis and alligator mississipiensis . a portion of mitochondrial nd4 and cytochrome b gene of 3 species of crocodilian was sequenced 百年来关于扬子鳄的分类地位存在着很多争议，本文利用测得的扬子鳄( alligatorsinensis ) 、暹罗鳄( crocodlylussiamensis )和湾鳄( crocodylusporosus )的mtdnand4和cytb基因序列，以及从genbank中获得密西西比鳄、凯门鳄和海龟( cheloniamydas )的nd4基因和cytb基因相应片段，构建以海龟为外群的系统进化树。
