Childrens’ Books on Fossils 3rd Ed., Fossilicious

  • History, 6-12
  • We know that history begins from the time the universe started. We want children to know history from the very beginning.
  • The second Great Story (The Coming of Life) designed by Dr. Montessori invites us to explore the first living organisms on Earth. The primary material that supports this exploration in a Montessori education is a Timeline of Life, accompanied by a workable timeline, and research cards.
  • Other excellent materials that can supplement this learning experience are the sets of books by Fossilicious. We used the second edition, which the children enjoyed reading several times. I was curious to discover the third edition, so I am sharing with you the differences that I found between the 2 editions (The 6 books on Fossils, yellow set).

Front/Back Cover

  • The newer booklets are one inch shorter (height), and have the same width as the former ones. They contain approximately the same amount of words/knowledge, and more.
  • The covers are colorful, thicker, and glossy. On the back, children can refer to the Geologic Time Chart to locate the period or era they are exploring.

Chronological Introduction

  • The former version began with facts about the living organisms described. The newer version begins by providing information about the time when the living organisms appeared. This information helps the reader situate the organisms on a timeline before reading about it.

Pronunciation guides

  • The former version contained pronunciation guides in parenthesis. The newer version does so too, but the words are described in a phonetic style that makes it easier for children to figure out.
  • E.g. Cambrian: “cām-bree-an” vs. “kam-bree-uhn,” or “sef-a-low-pod.” This one, I’ll let you guess.
How would you say this?

Font “sans serif”

  • I will take a guess that the former edition was written in the Times New Roman font, which uses character such as “a”, or “g” in a style that is not always familiar to young readers. Additionally, fonts like Times New Roman contain many “serif.” The serifs are the extra lines that finish letters, especially capital letters. It can present a challenge for some readers who are still decoding and reading phonetically.

  • The newer version is written in a friendlier and more familiar style. The letters are rounded, well spaced, and generous, close to a Sans Serif Style font. All letters are in a form that children initially learn to read and write. There is literally no serif.


  • The newer version contains words in bold characters. These terms are defined in captions on the same page as the bold terms. Children have immediate access to the definitions, which can help a young reader with reading comprehension, and retention. When a question arises, there’s a greater chance for retention of the answer when answered promptly (research-based).

  • In almost all books, dates have been updated, and are more precise. For instance, the former edition on Trilobites says that they “lived more than 500 million years ago,” while the newer edition says that the first Trilobites “lived about 540 million years ago.” This way, children can pinpoint each organism more exactly on a timeline.
  • In addition, some terms and graphics have been updated, either to facilitate understanding, or to provide more accurate scientific names.
  • Some proper nouns have also been capitalized unless in the former version.

In conclusion

  • In conclusion, I enjoyed the newer version. If I could choose, I would get the newer version because it is updated, and modifications have been made based on current findings, field testing, and feedback. They would also help my not-so-confident reader. I have put the books to work as soon as we received them. My 7 year old was able to read about 95% fluently. He was stuck on words such as “crinoid,” but started to get it with repetition throughout the book.

If you are guiding a large group of learners, I highly recommend you refresh your shelf with this new edition. If you are homeschooling or on a budget, you can still purchase the former version, and be plenty satified with it. If, like me, you currently have the former version, I hope this post will have helped you decide if you need the newer version.
