Paleontology Toys or How To Cover Your House With Plaster Dust

For Christmas last year, my then 5 year old wanted all things paleontology. And Lego. We opted for the former since we knew she had lots of Lego sets coming. We got her a great dig-your-own-fossil kit from National Geographic called the “Mega Fossil Mine Dig Kit“.

She’s done similar kits before, and loved them, but this kit really stood out for us for one reason: real fossils. If you aren’t familiar with these kits, they have small fossils embedded in a big plaster brick. It comes with a brush and digging tool and require lots of elbow grease. Similar kits we’ve tried had plastic replicas or plastic bones that can be put together. Those were fun as well, and she always enjoys getting messy, but something about digging actual fossils out of the plaster really excited her.

It took several evenings to dig out all the fossils, and each night, she would wash off her finds and then show them off to everyone. Once she finished, she set up a little museum and walked us around the exhibits. The kit came with a book about fossils, which we read with her, so she was able to tell us all about them.

The only downside to the kit is that the plaster is pretty solid, and she would get worn out scraping and brushing. It took a long time until we hit the first fossil, and she almost lost interest. I helped her get going, and once we unearthed our first find, she was hooked. Still, we had to take turns digging. Kids with more arm strength shouldn’t run into that problem. We’ve tried two other kits. One was very brittle and she demolished it readily. The other is even more solid and she eventually gave up on it. We’ll bring it back out this summer and try again. Oh, also, if you aren’t careful, you can get plaster dust everywhere. We set the brick in a cookie sheet to contain it.

By far, her favorite find was the coprolite, a.k.a. dinosaur poo. You can’t imagine the glee in her voice when she showed everyone her poo. We’ll have to turn it into a necklace. Maybe a good gift idea for next year, though she already wants a chewy toy necklace, so maybe that’s not such a good idea. In any case, this dig kit was a huge hit and helped keep her excited about paleontology. It has now surpassed “face painter” as her longest running “what I want to be when I grow up”.

Paleontology Party!

Fossilized mamoths from the La Brea Tar Pits

My child recently had a birthday. She LOVES paleontology, so she wanted a paleontology themed party, and I was in charge of activities. I thought about doing a “dig up your own fossil” project, but she’s done a lot of those, and they can take a while to complete. Not the best idea for a party full of kindergartners either eagerly anticipating cake or recently having ingested cake.

A few days before the party, I still didn’t have any grand ideas. We had some plastic dinosaur fossils as party favors, but I couldn’t think of any game involving them that didn’t also involve destroying our yard. Instead I borrowed my idea from Halloween: build your own monster dinosaur out of Play-Doh! It would be fun, but not strictly paleontologically themed.

Plastic dinosaur fossils

A friend of mine who is in the field once told me that paleontology sits at the intersection of geology and anatomy. So there I was, staring at plastic dinosaur skeletons and a bunch of Play-Doh and mulling over my options when inspiration struck! Why don’t we flesh out our own dinosaurs by smooshing Play-Doh onto the skeletons. Perfect! It would be fun and messy, but not too hard to clean up after. Also, it would give me the chance to talk about how paleontologists have to look at the bones and then try to figure out what the animals looked like on the outside by modeling the fleshy portions.

We had a wide variety of Doh colors to choose from, and each kid got to pick their favorite dino fossil. Then they went at it. Some tried to make realistic dinos, while others went for goofy (e.g. the Sweatersaurus who had evolved to survive the cold ice age). The party girl had recently been to the La Brea Tar Pits, so she spread out the black Doh and then walked her dinosaur into it so it could get stuck. Another girl didn’t want to get her fossil messy, so she made a flat piece of Doh, then make footprints. That was another teachable moment, since scientists often study fossilized footprints to learn about anatomy (the gait information can help figure out how the bones went together).

Play-Doh Dino Party!

All in all, the kids had a great time and took home their own creations — hypotheses about how the dinosaurs actually looked. If you’re curious, the Play-Doh came off pretty easily, so the whole project is reusable. We’ll definitely be doing it again.
