Common dolphin Ichtyor Ichthyosaurs were aquatic dinosaurs. They had dorsal fins and flippers that, at least superficially, resemble dolphins, even though their closest common ancestors were terrestrial reptiles that had neither dorsal fins nor aquatic tails. (See figure at right) Titelů The members of lineages between the dolphins and ichthyosaurs do not have adaptations such as -streamlined bodies -long ased with teeth -Ins and hopers 4.

You find some dinosaur fossils in rocks that overlie (are found on top of) an ash bed and that are cut by a volcanic dike. Using radiometric dating, geologists determine the age of the ash bed to be 120 million years (Ma) and the dike to be 100 Ma. What can you say about the age of the dinosaur fossils? Select one: O a. Their age is probably halfway between the age of the ash...
Female birds who practice polyandry might see benefits if they obtained genes from several partners who are particularly compatible with the genes in their eggs.
