This is great because it gets right to the point and is very easy to understand. I also like in the beginning how it said that sauropod means lizard footed.
It used to be thought that the sauropods had a second brain at the base of the tail. Paleontologists now realize that what they thought was a second brain was perhaps an enlargement in the spinal cord in the hip area (although this is not universally accepted), containing nerves and fatty tissue. This enlargement was larger than the animal's tiny brain and may have controlled the animal's hind legs and tail.
Sauropods are not heavily armed, but later versions of sauropods had some form of armor which was used as protection against other predators. Sauropods were plant eaters and had a very small brain hecause their head was very small. They were herbavores and ate mostley connifers.
Brontosaurus was one of the largest land animals that ever existed. The dinosaur Brontosaurus is now called Apatosaurus. This enormous plant-eater measured about 70-90 feet long!!!! and about 15 feet tall at the hips.
Evan, this was a very good site to learn about brontosaurus or apatosaurus. Apatosaurus have a small head which concludes that they have a small brain, and aren't the most intelligent species that had lived during their time. They had a long tail which acted as a counterbalanced to its very long neck. It also was a tool of protection from other predatorsYet the extremely long neck had advantages for a herbavore who would be constantly attacked by hungry predators. The apatosaurus was a very tall sauropod, which was taller than the allosaurus, which was a predator of the time. The allosaurus is not tall enough to try and snap at the head of the dinosaur, and it wouldn't be smart to get near a whip like like tail such as the apatosaurus's. It had a bulky body and ate rocks to help the digestion of its food.An interesting fact that i had learned was that their nostrils were located on the top of their head, but it couldn't be used as a snorkeling device because the apatosaurus lived on land and not near many big masses of water. I had peg like teeth, which resembling ones of a lizard today, and had four legs.
This website was very useful in talking about the apatosaurus. The apatosaurus was a plant eater (herbivore). This dinosaur had a small head and walked on four legs. The apatosaurus was one of the biggest land animals.
This is a really good website because it was talking about alls of the different dinosaurs that lived in the cretacious period. in this, we also more about the sauropods, which contributed to a great amount of chatter in class disscusion. Basically what we learnd here was that sauropods had gone extinct, but their relitive, which are lightly armored, roamed all of the continents on the now changing Pangea. We learned about Avian life, plant life, and Marine life, which at the time includedearly versions of fish and sharks, which contributed a lot since all of the marine life dinosaurs before had gone extinct.
I liked this website because it had a lot of information about the Cretaceous Period. It has what plants and animals lived during that period and how the Cretaceous Period ended (when an astroid hit).
Q and A with climate change facts! Good to quiz yourself with:) my favorite is: In the past, has Earth been warmer than it is today? If so, does that mean we shouldn't worry about global warming?
NASA (National Aeronautics Space Administration) and NOAA (National Oceanic and Atmospheric Administration) agree that climate change is happening and humans are contributing to it. Many people agree in the United States of America and abroad. MAny believe it is because of greenhouse gases from humans. Scientists are trying to answer some very important questions such as how quickly will the world warm, and what consequences will that have on certain parts of the world. The global temperature average has risen by 1.4 degrees Fahrenheit over the last 100 years. NOAA said that the decade between 2000-2010 was the warmest decade on record. 2005 was the warmest year on record. There have been more intense rainfall and severe heat waves. Sea levels are rising. The Earth does go through warming and cooling because of factors such as sun and volcanic activity. The warming and cooling is partly natural and partly because of humans. The sun's energy has fluctuated but is small in comparison compared to human's effect. The warming is consistent with what happens with heat trapping carbon dioxide. Carbon dioxide can lead to climate changes that can hurt plants, animals, and people. For every 2 degrees Fahrenheit raise 5-15% reductions in crops. 3-10% increase in rain which would create flooding. 5-10% increase in stream flow. 200-400% increase in wildfires in the western United States. Scientists predict that the temperature will rise 2-12 degrees Fahrenheit by 2100. It is not too late too fix climate change!
This website a natural process The Greenhouse Effect is a natural process that warms the Earth, and, in fact, is quite necessary for our survival. Gases in the atmosphere, like water vapor (clouds), carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2O) act as a natural blanket by preventing the sun's heat energy from radiating back into space, much like a greenhouse traps the sun's energy to warm someone's plants even in the middle of winter.
