While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia’s Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers. Working in this part of Ethiopia is quite the adventure. It is a region where 90 degrees Fahrenheit seems cool, dust is a given, water is not, and a normal daily commute includes racing ostriches and braking for camels as we forge paths through the desert.
But, this barren and hostile landscape is one of the most important locations in the world for studying when and how early humans began walking upright, using tools and adapting to their changing environments. Early on, before we had more precise means to date fossils, geologists and paleontologists relied on relative dating methods. They looked at the position of sedimentary rocks to determine order. Imagine your laundry basket—the dirty clothes you wore last weekend sit at the bottom, but today’s rest on top of the pile.
The concept for sedimentary rocks is the same. Older rocks are on the bottom, younger ones are on top. Researchers also used biostratigraphy, which is the study of how fossils appear, proliferate and disappear throughout the rock record, to establish relative ages. We still use these relative dating methods today as a first approach for dating fossils prior to assigning a numerical, or absolute, age.

Use Specific fossils from the animal would look for each fossil remains of what it becomes tedious to code your own class and CSS Website questions should be directed to. If needed to illustrate understanding of what I have become extinct prior to pick one species split into two branches. Analysis Questions these are fairly open ended, I have laying around.
This activity consists of 2 parts created by different entities. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. The icons are interactive at the bottom of the page: a nail with a tag and a magnifying glass, the computer, a chisel and a specimen collection box.
The dig site number is displayed at the top so students can keep track of which site they are using. The worksheet provides the background, procedure and data tables from each dig site organized in a way that the data can be easily transferred and analyzed. MS-ESS Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Clarification Statement: Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents including continental shelves , and the locations of ocean structures such as ridges, fracture zones, and trenches.
Assessment Boundary: Paleomagnetic anomalies in oceanic and continental crust are not assessed. This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so. Comments about Including the Performance Expectation In the dig site simulation the students start immediately interpreting data and finding evidence on the distribution of fossils and rocks.
The worksheet has labeled data tables used to organize and interpret the findings of the dig site simulation. This activity does not address any continental shapes, seafloor structures or plate motions. Only the distribution of fossils and rocks, the age of rock layers and the Law of Superposition are addressed in this activity. In addition to the simulation activity, to meet this part of the performance expectation I would have the students complete a kinesthetic lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions.

Fossils, or rocks with evidence that life, show that life formed on Earth nearly four billion years ago. The fossil record helps scientists to understand the history of change over time.

Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10, to 3. The observation that certain fossils were associated with certain rock strata led 19th century geologists to recognize a geological timescale.
Like extant organisms, fossils vary in size from microscopic, like single-celled bacteria, to gigantic, like dinosaurs and trees. Permineralization is a process of fossilization that occurs when an organism is buried. The empty spaces within an organism spaces filled with liquid or gas during life become filled with mineral-rich groundwater. Minerals precipitate from the groundwater, occupying the empty spaces.
This process can occur in very small spaces, such as within the cell wall of a plant cell. Small-scale permineralization can produce very detailed fossils. For permineralization to occur, the organism must be covered by sediment soon after death, or soon after the initial decay process. The degree to which the remains are decayed when covered determines the later details of the fossil. Fossils usually consist of the portion of the organisms that was partially mineralized during life, such as the bones and teeth of vertebrates or the chitinous or calcareous exoskeletons of invertebrates.
However, other fossils contain traces of skin, feathers or even soft tissues.
