Among famous groups of extinct organisms, trilobites probably rank second only to the dinosaurs in fame. Their fossils are instantly recognizable and often strikingly beautiful. In fact, prehistoric people liked them as much as we do. At Arcy-sur-Cure in France, a 15,000-year- old human settlement, one of the artifacts found by archeologists was a trilobite that had been drilled to be worn as an amulet.
- We watched Origins: How Life Began.
What was collected?
- Nothing.
What was assigned?
- Bring textbook on Monday.
- Geologic Time Line is due Monday.
- Chapter 6 Test is Tuesday.

Although the last few trilobites went extinct about 245 million years ago, they are one of the best-known and most-studied groups of fossil arthropods.

Daily Science Fact
Along the California-Nevada border north of Death Valley, the White Mountains, the Inyo Mountains, and associated ranges present one of the most important and best-known Late Proterozoic to Cambrian sections in the United States. Starting with the unfossiliferous Precambrian rocks of the Wyman Formation, paleontologists can work their way through a complete section that documents the appearance of various animals and protists, starting about 540 million years ago. Precambrian, Cambrian, and later Paleozoic rocks are also exposed to the south of the White-Inyo region, in Death Valley and in various ranges of the Mojave Desert.
- We continued the Geologic Timeline Project.

Daily Science Fact
The Marble Mountains are a rather small mountain range located in one of the harshest, driest parts of the Mojave Desert, in southeastern California near the tiny towns of Chambless and Cadiz. What makes the Marble Mountains especially attractive to paleontologists is the comparatively rich Cambrian fossil biota which can be found in a particular rock layer, the Latham Shale, that is well-exposed in the southern part of the range, as well as in some nearby ranges such as the Bristol Mountains. The Latham Shale and the rock layers below and above it comprise a well-studied section of Lower and Middle Cambrian strata, which extends, with some variation, over a large part of the southern Mojave Desert.

Daily Science Fact
The Cambrian Period marks an important point in the history of life on earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion", because of the relatively short time over which this diversity of forms appears. It was once thought that the Cambrian rocks contained the first and oldest fossil animals, but these are now to be found in the earlier Vendian strata.
- We read p.179-181.
- Workbook p.57-58.
What was collected?
- "Age of Rocks" notes with summary.
What was assigned?
- Section 6-4 Review Worksheet.

Daily Science Fact
With the exception of the possibility that there may be water ice at the poles of the Moon in craters that are permanently shadowed from the Sun's rays, there is virtually no water on the Moon -not running across the surface, not in the rocks. This eliminates a whole class of rocks found on Earth, the sedimentary rocks, that are formed by deposition or precipitation in water. There are no sandstones or limestones on the Moon!
- We continued notes on "Relative and Absolute Dating of Rocks".
- We discussed the importance of moon rocks.

Daily Science Fact
Cobra females produce a clutch of eggs each year and usually stay nearby to guard the eggs until they hatch. The baby cobra, like all snakes, is called a hatchling. The hatchling is able to take care of itself from the start and can spread its hood and strike on the same day it hatches. A large yolk sac remains in the hatchling's stomach to give it nourishment for up to two weeks before it needs to find food on its own.

Daily Science Fact
When you look at a frog or a toad, you'll notice that it doesn't seem to have a neck. Practically speaking, this is true. Most frog and toad species have large, protruding eyes so they can see in most directions. They can also hop around to look in another direction. But they can't turn their heads like we can, since their necks are almost non-existent.
- We took the Chapter 5 test.
- Read Sections 6-2 & 6-3 (Finding the Age of Rocks).
- WB p.52-56.
What was collected?
- Nothing.
What was assigned?
- Complete reading and WB.
