Mosasaurus: Mighty Ruler of the Sea - Smithsonian’s Prehistoric Pals

Age Level: Ages 0–5, Ages 5-8
By Developer: Oceanhouse Media

Mosasaurus lived over 65 million years ago during the late Cretaceous period. The Mosasaurus were not dinosaurs, but actually marine reptiles. Growing to as much as 55 feet long and weighing 20 tons, this sea and land creature was not one to be reckoned with.

The app takes you to a typical-like day of this enormous animal and conveys an atmosphere of what would have been. What was the Mosasaurus' diet? What enemies might be lurking to make him it's prey? Find this out and much more.

At the end of the story there are a few pages of information about the Mosasaurus, including a couple of the facts above. All-in-all very educational, and easy for a youngster to understand.

With all Oceanhouse Media apps, everything on each page is tappable, with the word of the item shown and said out loud. In addition, one can tap a word in the story to hear it again, or double tap to hear the sentence again. There are many other creatures from the same time period within the story, so if you're having a, “It's called a what?” moment, having the ability to see and hear the names again is very handy. Words are highlighted as the story is read. If you want to record and share your own rendition, they have you covered! The app is accompanied by great background music and sounds that one would expect in this time period. The artwork is fantastic!

Mosasaurus: Mighty Ruler of the Sea is one of 10 Smithsonian's Prehistoric Pal apps by Oceanhouse Media. Purchase it for $2.99, or get the whole bundle for $9.99. That's a nice savings for some stellar apps! Meet each featured dinosaur, as well as a slew of others that are incorporated into each story.

Compatible with iPhone, iPad, and iPod touch. Designed for kids 3-8.
