Cam Jansen realizes that three bones on a dinosaur model in a museum are missing and sets out to solve the mystery.

Ages 8-12

Cam Jansen's real first name is Jennifer, but her friends call her Cam because of her photographic memory. When she takes a mental picture, she says "click". In this story, part of a large series of mysteries, Cam and her friend Eric are touring a natural history museum. Cam remembers that one of the dinosaurs had more bones in its tail the last time she visited. The tour g
The original Cam Jansen series follows the exploits of 10-year-old 5th grader Jennifer "the Camera" (aka "Cam") Jansen and her best friend, classmate, and neighbor Eric Shelton. Cam got her nickname because of her photographic memory. All she has to do is say "Click," and Cam can remember everything she's seen, which comes in pretty handy when trying to solve mysteries.

David Adler has written several beginning chapter book series, but Cam Jansen is one of the earliest and most successful. He's b

David A. Adler, Cam Jansen and the Mystery of the Dinosaur Bones (Scholastic, 1981)

Straightforward early-grade mystery that's about as complex as an Encyclopedia Brown story, but takes up a good deal more space; one wonders at the expansive real estate. Still, mystery novels for kids were not a huge commodity back in the eighties (before the term “chapter books” had come about to describe this category of kidlit), and as with any vertical-market application, authors could get away with more, whi
Woohoo! It's only January 1st and I've already read a book!

Ok, I have to admit it's a chapter book and I've read it before (but not since 2nd grade). So, should it still count? Sure, why not?

I showed my 7 year old niece her mom's autographed(!) copy (the author visited our elementary school) and she asked if I could read it to her and, of course, I obliged.

Here are some thoughts while I read this out loud:
- This is the only book I read in the series, but Cam Jansen's red hair and signature "Cl

I really enjoyed reading this book! The main characters, Cam and Eric, are friends who seem to get involved with a lot of mysteries together. Cam's name is actually Jennifer but they call her Cam, short for 'The Camera". She got this nickname because she takes pictures of everything with her mental camera and says "click" as she is taking these mental pictures. In this book, Cam and Eric go on a class field trip to the Kurt Daub Museum with their fifth grade class. They travel around the museum ...more

Cam Jansen and her friend, Eric Shelton, are excited to be visiting the Kurt Daub Museum. It’s not their first trip there, but every trip is exciting – and the best part of all is the dinosaur exhibit! But as Cam studies the fossil of a Coelophysis, she realizes that something is wrong – some of the bones are missing!

Can Cam find the bones before they are used for some ill purpose?


Cam Jansen doesn’t used deductive reasoning to help her solve her cases. And she doesn’t spend all of her
This story is about how Cam Jansen and her classmates visit a museum and she notices the dinosaur has missing bones! The book makes me feel adventurous and not afraid to ask questions while being smart about it. Cam has photographic memory which is why she is able to compare with an earlier “photograph” of the dinosaur skeleton and note that it had missing bones! Cam and her friend Eric follow the clues to finding out who/what was behind the missing bones. The theme of the book is following your ...more

I remember reading one of the Cam Jansen books when I was younger but I cannot put my finger on it. More than likely it was this one but again my memory won't place it.

Anyway it is a basic and short read that will be great as a step-up book. There are a few words that may end up causing problems but with the dinosaur names at least there is a pronunciation guide for those who don't know them. Otherwise word-wise there shouldn't be much other problems.

There isn't much of a plot or background t

Recommends it for: children starting to read chapter books
This is a reread for us. Our girls picked this one out and I thought it would be worth a second read. We'd read the Cam Jansen Double Mystery #1 more than two years ago, and I was pretty sure our girls wouldn't remember the story. It's an entertaining story and I like that Cam and Eric solve the mystery; I don't like that they go off without parental supervision and put themselves in danger. Still, it's just a story and the drama adds to the enjoyment of the tale.

Overall, it's a fairly typical
This is the second young reader chapter book series that I have introduced to my 3.5 year old. He's hooked! He keeps sitting down with the book and pretending to read it. He was able to comprehend the story and it kept him engaged throughout (we read it all in one sitting! ). Will be reading again and looking for more in this series.

I also remember Cam from my childhood and I remember now how much fun her adventures were!

A great mystery/detective series - a great novel for young children (easy to read). For those who like Harriet the Spy and Encyclopedia Brown.

This book left me wanted more and more mystery. This plotline had much action and a thrilling series of events. I liked this book because Cam is a relatable character. I can see other children that I have never who are just like her. I think Cam would be a great role model for little children. She always does the right then and wants to help others. I would use this in a future classroom to talk about heroes. I think children should learn about heroes and what is right and wrong at a young age s ...more
Fun book. This book has the perfect co
mbination of suspense and morals all wrapped up in a plot kids love...dinosaurs
This was my first chapter book! I want to read more Cam Jansen books now.
cam was going to a mueasm then she saw one of the bones were missing.

Cam's plan to solve the case certainly led to no disgrace.
Not the authors best work.
I was recently asked to make a list of ten books that made a long-standing impression on me. The Cam Jansen mysteries were on that list, so 25 years after reading them I decided to give one another try. Definitely not as thrilling now as when I was kid, but I'm still jealous of Cam's photographic memory and the fact that her best friend in school is a boy! :-)
Jennifer Danko
A fun adventure book for second grade students, this easy read will capture student’s attentions that are learning to read. The illustrations allow for further development of the imagination while reassuring the student they are reading correctly. Cam’s adventures test her friendship with Cam and her will to solve mysteries. Children between the ages of seven and ten will appreciate Cam’s need for adventure.
Andd Becker
Love the Cam Jansen concept!
This little girl is a bit annoying, and has some whack friends who follow her blindly into danger just because she has a photographic memory. Her dad is always propping her up on a pedestal for having such a great memory when he should really be disciplining her for always snooping around in other people's business and trespassing. This book is alright though, it's got dinosaur bones in it.
Samantha Glasser
I've always loved mysteries, so when our class went to the library to check out some books and I saw this series on the shelf, I snapped them up one by one. I thought the concept of a girl with a photographic memory was so cool and imagined how I could use that skill in my own life. Unfortunately, I never developed that ability, but I remember these books fondly.
oh my god! ever since i read this book many many years ago i have been captivated by the notion of a photographic memory, and i have attempted many a time to blink my eyes like cam to commit a scene to memory that i can file away and inspect later. wow, finding this on goodreads was a gem!

I always loved Cam Jansen books as a kid, and it was fun reading one again. I think for me she came after Nate the Great and before Encyclopedia Brown. I would definitely recommend this series to both boys and girls interested in mysteries.
I'm in the process of reading all my collection of children's books. I'm undecided on how to rate the books..from an adult or child's I'm going to go with the adult viewpoint. Cam was just plain annoying and the "mystery" was silly.
Cam's third mystery has her and Eric looking for lost dinosaur bones after visiting the museum. Cam's photographic memory has them biking across town in search of the thief.

When I was younger, this was one of my favorite series. Reading them now, they are pretty simplistic, but they were fun easy to read mysteries, and it's very enjoyable to share those same stories with my niece now.
