Invertebrate fossils.

Devonian Period, in geologic time, an interval of the Paleozoic Era that follows the Silurian Period and precedes the Carboniferous Period, spanning between about 419.2 million and 358.9 million years ago.The Devonian Period is sometimes called the "Age of Fishes" because of the diverse, abundant, and, in some cases, bizarre types of these creatures that swam Devonian seas.Fossil activities for kids are a fun way for kids to find fossils in their own neighborhoods.

Although often overshadowed by the state's vertebrate fossils (such as sharks' teeth or the skeletons of huge swimming reptiles called mosasaurs), Kansas invertebrate fossils are nonetheless scientifically significant.Scientists have long puzzled over the gap in the fossil record that would explain the evolution from invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds ...

Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species). The body is covered in a shell that is made of two halves (valves) that are held in place by muscles. The valves can be opened (by the muscles) at one end to allow water in ...Technically, sea squirts are called tunicates, and they represent a marine invertebrate that is part of the phylum Chordata, a group of creatures that includes all animals with dorsal nerve cords or notochords.Vertebrates are a sub-group of the chordates. The adult form of the sea squirt is a stationary bag-shaped creature (Figure 1) that typically attaches to ocean rocks around the world.

/ Invertebrate Fossils / Graptolites. Graptolites are tiny, extinct animals that lived together in groups or colonies and shared the same skeleton, which was like an apartment building.

The best places to find fossils are near bodies of water. As you search by the shores of streams or lakes, look for sedimentary rocks. You can pull these rocks apart with your hands, and you often find fossils, small shells, and invertebrate bones. Fossil hunters divide Georgia into three parts: Northwest, Northeast, and Southern.
