Tracking Ghosts that lived long, long ago

It’s that time of year again when leaves begin to fall, and darkness overtakes the amount of daylight. There is a spookiness in the air. In the spirit of learning about terrifying creatures this month, we are seeking the ghosts of dinosaurs.

Dino Tracks illustrated by Cathy Morrison, written by by Rhonda Lucas Donald

Can you imagine a 40-foot-long, 12-foot-high lizard with thousands of pointing teeth? What about a flying, swooping lizard the size of a plane with a MASSIVE beak? These animals all lived millions of years ago and have disappeared, but they did leave a trace of their existence.

We are headed on a hunt to find dinosaurs and other extinct creatures around the country, and here are some of the best places to see them.

I am Allosaurus written and illustrated by Timothy J. Bradley

Cleveland-Lloyd Dinosaur Quarry – Elmo, Utah

 More than 12,000 bones have been found at the site, mostly from carnivores and primarily the Allosaurus. Get a glimpse of bones and rock formations in a landscape that was once a very active spot for many meat-eaters especially flying giants.

Dinosaur Valley State Park – Glen Rose, Texas

 Walk, or paddle the riverbed to see the mark dinosaurs left on their former home. Here you will find tracks from sauropods and theropods intertwined in various locations. These tracks gave scientists valuable information in piecing together some mysteries of the past.

Dinosaur State Park – Rocky Hill Connecticut 

 Go below the dome to find one of the largest collections of dinosaur tracks in North America. The tracks are attributed to the Dilophosaurus and were made about 200 million years ago. After viewing the tracks, explore trails surrounded by some of the foliage related to the plants dinosaurs once walked through.

Dinosaur Ridge – Morrison, Colorado 

 Denver as a tropical oasis? Hundreds of tracks are set in stone just outside the city with evidence of Brontosauruses, Iguanodons, Triceratops, alligator ancestors, and fossilized palms. The trail has all sorts of surprises buried in the rocks.

La Brea Tar Pits – Los Angeles, California

 The Ice Age comes alive in the heart of Los Angeles. The tar pits have been there for thousands of years and captured various animals for thousands of years. Watch paleontologists actively uncovering mammoths, saber-toothed cats, and dire wolves and explore the museum filled with fossils of unlucky animals.

Is it a bird, is it a plane, is it a dinosaur?

Yep, that’s right, scientists have been studying the connection of today’s modern birds to their long-lost relatives, the dinosaurs. For many years, paleontologists believed that all dinosaurs were just giant lizard-like creatures.

Relatively recent discoveries in China have changed the minds of many scientists. This area of Northeastern China has attracted paleontologists to explore the lake and volcanic ash deposits abundant with ancient fossils. These fossils are bird-like in structure and lead to the newly held belief that many dinosaurs were feathered.

A local farmer dug in the rock and knew he had something special when he found the first fossil of Confuciusornis (sacred bird of Confucius). The fossil, about the size of a modern-day crow, had a beak and feathers with a long plumage tail. Since this discovery, more digging into the rocks in the region has unearthed other ancient flying dinosaurs, protopteryx, Sapeornis, and Yanornis. 

But these are not the only flying dinosaurs. Long before Confuciusornis, Archaeopteryx was dated to have lived 150 million-years-ago, and part of the Avialae clade. These are the closest relatives to modern birds. They had larger braincases, feathers, and pneumatic bones like today’s birds; but also had teeth, three-fingered hands and claws, and a long, stiffened tail like dinosaurs.

But when you ask a child about ancient creatures of the sky, most will answer with the pterodactyl. The pterodactyl is one type of Pterosaur that ranges in size from a fighter jet to a sparrow. With HUGE heads, long necks, heavy bones, and stiff skin-like wings, these flying lizards were terrifying carnivores to the dinosaurs living below.  

The Pterosaurs evolved significantly over time. They lived from 251 million years ago to 66 million years ago, and in that time, some species got larger, while others showed different ways they took off for flight. But the most baffling to many scientists is how they were able to hold up their giant heads. Paleontologists at the University of Illinois at Urbana-Champaign have recently had a breakthrough modeling how the vertebrae were arranged to create a strong structure.

We are excited to introduce a relatively new pterosaur to young readers this fall, the Hatzegopteryx. They were giants of the sky and believed to be a dominant predator in the area now known as Romania. The first fossil was found in 2002 in Transylvania. 

Timothy J. Bradley’s story, I am Hatzegopteryx follows a Hatzegopteryx from egg to extinction as he grows and learns to soar. Written in simple three-word sentences, even the smallest dinosaur enthusiast will be reading this book in no time.

Because of science, we know we can, but should we…

Recently, I was listening to a conversation about dinosaurs and the new Jurassic World movie. This made me think, what if we really could bring back a dinosaur? Is it really a good idea?

Biologists, paleontologists, and other types of scientists have made major advancements in studying fossils and extracting DNA information. For example, just a couple decades ago all dinosaurs were thought to be scaly green creatures. Now, we know that many of the dinosaurs had feathers and were very brightly colored.

Other advancements have been made in animal science. In 1996 Dolly the Sheep made news as the first sheep cloned from an adult cell. Other scientists have talked about the ability to reintroduce the woolly mammoth.

It would be amazing to think of a T-Rex stomping through the backyard. I don’t know if I want to see a beast the size of a bus coming toward me with those teeth especially after seeing the movies.

If your little ones want to learn more about dinosaurs, here is a short Arbordale reading list.

Dino Treasures
by Rhonda Lucas Donald & illustrated by Cathy Morrison

Just as some people dig and look for pirate treasure, some scientists dig and look for treasures, too. These treasures may not be gold or jewels but fossils. Following in the footsteps of Dino Tracks, this sequel takes young readers into the field with paleontologists as they uncover treasured clues left by dinosaurs. Readers will follow what and how scientists have learned about dinosaurs: what they ate; how they raised their young; how they slept, fought, or even if they ever got sick. True to fashion, the tale is told through a rhythmic, fun read-aloud that can even be sung to the tune of Itsy Bitsy Spider.

Dino Tracks
by Rhonda Lucas Donald & illustrated by Cathy Morrison

Step back in time and follow dinosaur tracks around the world. Whether made by a few dinosaurs or large groups, these tracks provide clues to the movement and behavior of these lovable ancient creatures. What dinosaurs made the tracks and what do scientists think they were doing when they made them? The author tells the story in rhythmic rhyme that may be sung to the tune of Over the River and Through the Woods.

 

Wandering Woolly
written & illustrated by Andrea Gabriel

Little Woolly leaves her mother behind as she chases a toad down to the river. When the glacial ice breaks, she is swept away in the rumbling, rolling water. Now alone, the mammoth calf struggles to survive. She must sneak past cave lions, bears, saber-toothed cats and humans. Exhausted and afraid, she must even hide from stormy weather as she fights her way back to her herd. How can she find them? Will she ever get back?

 

 

 

Decoding Dino Tracks

If you ever take a stroll through the historic streets of Charleston, South Carolina you will probably hear the guinea fowl before you see them. Among the mansions and historic sites a flock of these birds roam free. Now scientists at Brown University have employed this chicken-like bird to help understand more about how dinosaur tracks formed, how dinosaurs moved and how the soil structure impacted the tracks.

The scientists are using x-ray video and poppy seeds to get a better understanding of how tracks were made and preserved over so many years. This also gives them insight into how dinosaurs walked and moved across the land. Watch here:

Paleontologists are constantly learning more about how fossils were created and learning more about the animal itself. Author Rhonda Lucas Donald is fascinated with dinosaurs and the field of paleontology, her book Dino Tracks is a great introduction to tracks and how they are found. The follow-up Dino Treasures is coming this January and goes further into how paleontologists have discovered different traits of these large beasts through the artifacts they left behind.
