Answer 1

How do forams from the cretaceous period differ from forams from the tertiary period in terms of morphology.

The foraminifera are also referred to as forams. They belong to the phyla ameboid protists which have granular e toplas, that is used for catching of food. A known phenomena that led to extinction of the forams was the Cretaceous tertiary extinction. The foram species that had been see. In the Cretaceous period, just at the boundary of the K-T extinction, had been larger as compared to those that were found in the tertiary period. As compared to the tertiary period forams were more elaborate in the creataceous period. The forams in tertiary period were after the K-T extinction. After the extinction the forams started becoming less elaborate and smaller in size. This implies that larger sized forams had become extinct.
