Introduction to Paleobiology - Monday, 1st Period
It was back to normal this week and both teachers were standing in front of the class.
“Good morning,” Cutter smiled as he began that week’s class, “this week we’re going to be looking at Micropaleontology, which is the branch of palaeontology that studies microfossils. And microfossils are fossils that are generally not larger than four millimeters, and commonly smaller than one millimeter and you need a microscope to study them. Every kingdom of organisms is represented in the microfossil record and they can provide important information about ecology in the past”
“Microfossils are most common in sediment that forms beneath water, particularly ocean water or lake water , very old microfossils may also be found in rock,” he explained, “Special techniques are used to separate microfossils from rock. For example, the shells of diatoms and some other organisms are made of silica; other materials in the rock can sometimes be removed with acid, leaving just the silica shells,” he smiled over at Connor for him to continue the lecture.
Connor nodded and gave a small smile as he picked up his notes to continue the class.
“Micropaleontology can be divided into four areas of study. The different areas of study use different techniques to separate the microfossils from the material they are encased within. This is because the microfossils are made of different minerals and stand out from the other minerals in the rocks and stones around them. Most microfossils are made of one of the following: Silicon dioxide, for example in the shells of diatoms, Chalk, for example in the shells of coccoliths and foraminifera, Phosphate, for example in bones of vertebrates, Organic compounds, for example in pollen and spores. And while they are very small, they are still important bits of the fossil record. It is these tiny fossils that have helped us understand more about ancient oceans, extinction events, and the way plant and animal life evolved on the Earth. “
Connor looked back at Cutter so he could wrap up the lecture while he got the activity for the day set up.
“For our class activity today we’re going to be looking at some slides of microfossils and I would like you to fill in the worksheet as well with your notes and observations. As always if anyone has any questions myself and Mr. Temple will be happy to answer them for you,”

Had she actually been promised any, either before or after she'd signed up for the class? Not at all, but she was hardly going to let that stop her from sulking about it.
