The explanation they consider most plausible is behavioral differences between extinct and present-day carnivores-in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species.
The explanation they consider most plausible(subject) is behavioral(object) differences between (extinct and present-day carnivores)-in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species(后面补充说明的成分).
他们认为最合理的解释是extinct和现在的carnivores的行为不同。特别是extinct的species中,捕猎的牙齿和被捕的动物骨头有更多的接触。
这句话说明,因为骨头和牙齿很多接触,所以可以得到下文的结论:食物之间的竞争比较激烈。食物争抢比较厉害。
