Archaeopteryx

The Archaeopteryx was a prehistoric bird that lived during the Jurassic Period. It was 2 to 3 feet long with lots of hollow feathers for flying. It was a meat eater. It had a big claw on it's feet for hunting.

It could dodge trees while flying. But, it did not flap it's wings. It glided through the air. It did not have the strong chest muscles of birds today. It had a different type of tail than birds today. It's tail was very long. It is believed to have had black colored feathers on it's wings.

The Archaeopteryx had a bigger brain than dinosaurs. It is thought to be one of the first examples of how the dinosaurs evolved.

Dacentrurus

The Dacentrurus was a large Stegasaurus type dinosaur. It was an herbivore that lived in the woodlands of Europe during the Jurassic Period.

It was 6 feet tall, 4.9 feet wide, 26 feet long, and weighed up to 5 tons.

It had plates and spikes on it's back. These were placed in the skin in rows along it's spine.

I feel sorry for these dinosaurs with all that armor. I imagine it was very heavy and made it hard to walk.

Iguanodon

The Iguanodon was an herbivore. He had a sharp thumbnail for defense. He could grasp things like tree limbs with his front feet. He had bird hips.

He had a beak and teeth to chew his vegetables. He was one of the largest ornithopods.

He was the 2nd dinosaur discovered. Dr. Mantell discovered the Iguanodon. He placed the thumbs on Iguanodon's nose, thinking it was a horn.

You can see Iguanodons in Dinosaur by Disney. I like that movie!

Dilophosaurus

The Dilophosaurus was a meat eater from the Jurassic period. It was fast. It had 2 big combs on it's head. It walked on 2 feet.

The Dilophosaurus was featured in the Jurassic Park movies, but it did not really spit poison or have the frill around it's neck.

The Dilophosaurus had thin, bent,curved teeth. Paleontologists believe he could have been a scavenger because his teeth were not strong enough to hunt big things.

De-Extinction Question

A friend of my Mom's posed this question to me today. Thank you, Mr. Hatley for your question!

This question is directed toward Gabe - Scientists believe they can rebuild or revive extinct animals from DNA. If this is in fact true, how would you feel about dinosaurs being revived? If you are for dinosaurs being revived, which ones should be revived? Should we release them into the wild, a zoo, etc? If you do not think the revival of dinosaurs or other extinct animals is a good idea, why not? Thanks, I will hang up an listen :-)

Here's my answer after reading 2 articles about De-Extinction.

I'm for reviving dinosaurs. The ones that should be revived are the vegetable eaters, herbivores, because they can't eat my head off!

I would get this island and release them into the wild.

With just the right technology, they can bring back other extinct animals. Then dinosaurs is a possibility; but, it will take many years of testing.

The hard part is going to be finding live DNA cells of the dinosaurs. I will warn you not to do like "Jurassic Park" using blood from mosquitoes; because, you wouldn't know what dinosaur you had. You could have a meat eater you don't want.

You want to dig up bones and get the DNA from the bone marrow.

Again, thanks for the question!!

Ankylosaurus

The Ankylosaurus was as tall as an 8 year old and long as a house. He was an herbivore, vegetable eater. He had an armored back. He even had armored eyelids! He had a club tail. He might have used his club tail to fight other Ankylosauruses or dangerous predators, or both!
He had a brain the size of a walnut. Paleontologists believe Ankylosaurus might have had a second brain in his club tail.

Stegosaurus

Stegosaurus was tall as 1 and a half men and long as a house. It had plates on it's back and spikes on it's tail. They believed the spikes on it's tail might have been used in defense. The plates could have been used for temperature regulation keeping it cold or warm. It could have pumped blood into the plates which helped intimidate predators or attract a mate.

It had a very small brain the size of a walnut. It might have had a second brain at the base of it's back bone for controlling it's tail. Paleontologists believe it might have just been a bundle of nerves; but, they are not sure.

Stegosaurus was a plant eater so it was an herbivore. It ate plants down low on the ground. It could only walk about 4 miles an hour because it's legs were so short.

Ammonite

Ammonites were meat eaters that ate plankton and little fish. They had a hard shell that other fish could not bite through. They had air chambers in their shell they used to jet around in the ocean. This air helped them float, too.

It was a type of prehistoric squid inside the shell. The shells could get up to 3 feet across with the girl ammonites being bigger than the boy ammonites. The girls laid their eggs inside their shells.

They had a lid on their shell that would open or close. It was open when they had their heads out; but, they could pull in their head and let the lid close when a big, scary monster came by.

Long Necks are Sauropods

Long necks are really called Sauropods. They are the largest group of dinosaurs that roamed the earth. There were many breeds including the Camarasaurus (Mom wonders what kind of pictures they took), Brachiosaurus, Diplodocus, Apatosaurus/Brontosaurus, and the Supersaurus.

Long necks were as long as a tennis court and over 4 stories tall. They had to eat about 440 pounds of vegetation per day. That's equal to almost 9 rectangular bales of hay. They were herbivores, which meant they were vegetarians.

The Apatosaurus/Brontosaurus had 1 weapon, a whip like tail. The tail could move so fast it could break bones.

The Sauropods traveled in herds. This protected the smaller long necks from the vicious carnivores. The carnivores would not attack the grown long necks. The grown long neck would whack it with it's tail or crush them between their toes.

Pteranodon

The Pteranodon was a flyer. It was a fish eater with no teeth. It would fly over the water then dive down and catch a fish.

It lived about 65 million years ago.

It had a huge claws on it's feet but it did not use them for catching fish.

It had raw-hidey wing skin. It's wings were attached to it's hands and legs.

It had a huge crest on it's head used for balance during flight. It also was used to impress the females.

It flew in air currents. It lived on rocky cliffs near ponds and oceans because that was where the fish lived. They lived on the cliffs because they couldn't get good air from the ground. On the cliffs they picked up air currents that could carry them a long ways.

Duck Bills

The duck bill family, Hadrosaurs, is very interesting. It makes me go quackers! Each one in this family of dinosaurs has a crest. Scientists think Parasaurolophus might have used his crest for snorkeling and sounds. It might have helped him have a better keen sense of smell. It might have also helped the males in finding a girlfriend.

This dinosaur has a bill like a duck with many, many teeth for eating plants. He actually chewed his food! He constantly lost teeth; but, they were always replaced by new ones.

Duck bills had a stiff tail that kept it from swinging back and forth. His tail was used for balance. I'm sure it helped him when he stood on 2 feet or all 4 feet.

Velociraptor

In the book titled DK Guide to Dinosaurs by David Lambert it shows a picture of a velociraptor and a protoceratops together. Velociraptor hopped up on a protoceratops and the protoceratops knocked it off. The bones were found with Velociraptor's arms around the protoceratops snout and it's legs kicking the throat. I liked that picture of the fossils.

The Velociraptor has big claws on it's back feet that are retractable like a cat's claws. In attacks the claw was lifted higher than normal into the air.

Paleontologists believe the Velociraptor used a scissor-like hand movement for fighting. They had to fight because they were meat eaters. When it attacked it would have it's arms forward out in front of it. When it wasn't attacking it's arms were folded back like a chicken's wings.

The Velociraptor was the same size as a modern day, domesticated turkey at 2 1/2 feet tall, 40 pounds, and 5.9 feet long.

Paleontologists found in 2007 that the Velociraptor had feathers because they found quill knobs in a fossil. It couldn't fly because it only had a few feathers to help keep warm. It also used the feathers to keep the nest warm.

Tomorrow, I'm studying the duck bill dinosaur.
