by: Julie Ball  (1998) Soldotna, Alaska

Elena raced to the village council office after school. She went bounding into the door and slid to a stop in front of Ms. Coleman's desk. Now that she was there, she didn't know exactly what to say. "I was... I mean I thought I would just stop by and see, you know, what was going on." She knew that not much could have happened since yesterday, but she just couldn't stop herself from trying to get some sort of new information.


"Elena, this is going to take time." Ms. Coleman replied patiently. The native corporation is going to have to find a paleontologist qualified to do the excavation, and try to get a government grant to pay for it. Then the paleontologist will have to write up an extensive plan on how he will excavate the find and submit it to the state for approval.

"So, how long does all that take? It's September now, in a month there will be snow on the ground." Elena asked downhearted.

Ms. Coleman looked sympathetic. "You're right, there probably won't be any major work done until next summer. On the bright side, Mr. Evanoff was talking to a professor at the University of Alaska. The professor's name is Dr. Parker. He is very interested in your dinosaur bones. If the weather is good Saturday, he will be coming out to take a look."

"Yes! Yes! Yes!" Elena exclaimed. "Is he qualified to do the excavation?"

"I suppose so... He's the leading authority on Alaskan dinosaurs." Ms. Coleman had already turned back to her work. "You'll just have to see if you can talk to him on Saturday."



Elena wiggled through the remaining four days of school. She spent every morning on the Internet and every afternoon in the library. The rest of the time she spent sketching pictures of the bones and how they might fit with other bones. Sketches of whole dinosaurs and parts of dinosaurs. Her teacher, Mrs. Carmen, was very impressed with how dedicated to her dinosaur research Elena had become. She had however; asked her to put her sketchbook away until after she had done her math.

Saturday morning was clear and crisp. The stars were still shining when Elena woke up and tiptoed into the kitchen to pour herself a bowl of cereal. She was sitting there organizing her notes when her mother came out to start the coffee. Her mother yawned and looked at her bleary-eyed. "Do you know it's Saturday?" she laughed. Elena had been doing an hourly countdown since Monday after school.

Elena smiled sheepishly. "Do you think I'll be able to talk to Dr. Parker Mom? I've been so excited, and now I'm worried he'll think I'm just some kid..."



"There is no way to tell how other people will act Elena. Mr. Evanoff did say that you could come along to look at the site with them. I'm sure Dr. Parker will be impressed with you. Not only did you find the bones, you knew what they could be and told the right people. Then, as if that was not enough, you've been doing your own research. Even if you just get to listen in, you will have the opportunity to learn a lot of new things. "

Elena sighed, "That's true, I've just suddenly gotten nervous." The sound of an airplane interrupted their discussion. Elena jumped up, That's the 8 o'clock flight from Aniak. Gotta run." Elena grabbed her school backpack and headed for the landing strip.

Mr. Evanoff and some other council members were standing at the edge of the runway, talking to a tall bearded man. Elena leaned her bicycle against one of the airport sheds and walked shyly toward the group.

"Well, here she is, our own resident paleontologist," teased Mr. Evanoff in a friendly way. "Elena, I would like you to meet Dr. Parker from the University of Alaska. Dr. Parker, this is Elena, she is the one who found the bones."

"It's very nice to meet you, Elena," Dr. Parker replied. "Everyone has told me so much about you. Could you tell me a little about how you found the bones?"



Elena looked up at him with a grateful smile, and began to tell her story. She finished by pulling out her notebooks and showing him her sketches.

Dr. Parker was obviously impressed. "I see you have the makings of a real paleontologist here, Mr. Evanoff. I can see why you are all so proud of Elena. Shall we have her show us the bones?"

Elena quietly put her books back into her backpack, but inwardly glowed with the praise and excitement.

The group rode four wheelers as far as the berry-picking field. After that they hiked the same trail Levi had scrambled up. Remembering that it was Levi who had really found the bones, Elena told Dr. Parker about how Levi had thought they were dog bones. She felt humbled to remember that it was not really her own find. Levi really shared the credit. She would be sure not to complain next time Mother asked her to watch him.



When they reached the shale hillside, Elena showed Dr. Parker the bone fossils. Dr. Parker opened his backpack and took out a camera, a measuring tape and some other tools. Dr. Parker took a brush and brushed the dirt and dust off of the bones. Placing his measuring tape next to the fossils he photographed each of them. Then he took out a notebook and began to take notes.

Elena waited as patiently as she could throughout Dr. Parker's inspection. She wanted to ask him a million questions. She sat on her heels watching him, her lips pressed together to keep from blurting out. After Dr. Parker was done writing, looked up at Elena and smiled. "This is an amazing thing you have found here Elena. Do you see this fossil of a shell? This is a fossil of an Innoceramu.

An Innoceramu is an index fossil. That means that this kind of animal only was around for a relatively short time in history. So, if you find one, you know about when the rocks around it were forming. So, what this tells me is that the rocks formed around these bones in the Late Cretaceous Period of the Mesozoic Era.

Innoceramus Fossil



Elena was both excited to get this definite information and a little bit disappointed. The dinosaur she had thought it might be was not from the Late Cretaceous Period.

She looked through her notes to where she had written about Mesozoic Era. "It seems like there were a lot of different dinosaurs and marine reptiles in Alaska during that time period, the ankylosaur, the ceratopsian, and the hadrosaur (a) and (b). How will you figure out which one it is?" Elena questioned.

"Well, the bones are fairly large and we will compare the bones we find with other bones that have been identified. Then we will decide if this is a dinosaur we already know about or, if it is an entirely new dinosaur." Dr. Parker answered.

Elena had never considered that the bones she found might belong to a dinosaur that had never been discovered before. That idea was more exciting than ever.

"If it is a new type of dinosaur we will try to figure out what family of dinosaurs it belonged to. It is unlikely, though, that it would be an entirely new kind of dinosaur," continued Dr. Parker.



That evening Elena sat at her desk going over her notes. "I will choose another dinosaur that I think it could be. I've already been able to eliminate quite a few possibilities. The dinosaur is from the Late Cretaceous Period. The bones are too big to be one of the smaller dinosaurs. So, I will guess it is a __________________________ .
