Dinosaur Birthday Party Ideas

Alright, so let’s start on a more macro level. Your child loves dinosaurs and has chosen (or you’ve chosen if they are little bitty) to have an all things dinosaur-themed birthday party. 

If you go to the trusty internet and type that in, you’ll have more ideas that you can shake a stick at, and you’ll promptly shut your laptop in a fit of overwhelm, only to revisit the topic a mere two weeks or so before the big event (no judgment here, that’s me in a nutshell).

So start here, friend. These ideas will get you started and simplify the search. What’s not to love?

Dinosaur Invitations

One of the first things you’ll need to do after you’ve decided on a date and time is to find a cute dino invitation, and there are lots to choose from! Your invitation will help you set the theme for the party. 

1. Roar! Roar! Roar! Printable Invitations

Product Features

  • Download file arrives instantly via email
  • Customizable
  • Cute color scheme!
  • Appropriate for wide age range

We love these for their sleek graphic design and adorable color scheme. These are likely best for older kiddos and not infants (but you do you!). You can download it on any device and edit from there. Keep in mind that you’ll have to have them printed yourself–this is just the downloadable design.


  • Low price

  • Easy to download and customize

  • Simplistic, cute color scheme


  • You have to download and print them yourself

  • You’ll need some extra lead-time for downloading/printing

Like the idea of printable invitations but don’t love that particular design? Try one of these:

  • Historic Dino Bash Downloadable Invitation–classic design and would be great for a girl’s dino party if you’d like something a little more pink. We’re not saying you have to go pink for a girl’s dino party–just mentioning that in case it’s more your little one’s speed.
  • Stomp on Over Downloadable Invitation–this is a great design for little ones. With sweet pastel colors, it’s a great way to set your color scape for the party. 
  • Explorer Downloadable Invitation–got a 5-9 year old who fancies themselves an explorer? This one is super cute. 

2. Double-Sided Dino Cutout Invitations

Product Features

  • Four different cut-out dinosaurs
  • 24 to a pack
  • Double-sided
  • You (or you + your kiddo) fill in date/time/place
  • 8×5
  • Appropriate for ages 3+

Got a little one who enjoys practicing writing and might want to help fill out their own invitations? We love these fun, double-sided cutout invitations! The pack includes 4 different dinosaur shapes, so your child can pick which dinosaur they want to send to which friend! The package says “for boys,” but we say screw that. If your daughter loves dinos, why shouldn’t she have a dino party?!


  • You fill in the party details, so no printer involved!

  • Unique cut-out design

  • Get your kiddo involved by letting them help fill in the information if they are learning to write


  • Reviewers suggest using a permanent marker as regular ink can smear

  • Some reviewers say the space to write in is a bit small

Like the idea of your kid helping fill out their own invitations but don’t love this design? No worries! Try these:

3. Stomp! Chomp! Roar! Let’s Party Like a Dinosaur

If you’re anything like me and have great intentions but are pretty sure you will not actually get the invitation template you downloaded printed, then honey, you should just go straight to a printing service like Zazzle.

Yes, you are going to pay more to do it this way, but if it saves your sanity and it’s in budget, I say go for it. This delightful 5×7 design would be great for infants or younger kids! It’s editable, and you can choose the number you need.

Dinosaur Birthday Decorations 

Once you have an idea about what you want your invitations to look like, you’re now ready to move on to decorations! Your kiddo needs some pretty great dinosaur themed birthday party decorations, right?? Right. 

Let’s talk about how to accomplish this first:

  • Look closely at the color scheme of your invitations and note three primary colors. These are now your color scheme for party decor! 
  • What’s the design of the invitation like? If the design is more Jurassic Park and appropriate for older kids, you’ll want to continue that vibe. If the design is softer, with a more muted tone for younger kids, then keep that vibe for continuity.

1. Dinosaur Balloon Arch 

Product Features

  • 171 pieces with 4 foil dinosaur balloons included
  • Comes with materials to put it together (dot glue and ribbon)
  • Appropriate for a wide age range, just make sure to watch out for small pieces around little ones!

Balloon arches are super on trend right now, and honestly they really are a great way to make a big (easy to assemble!) statement for your dinosaur themed birthday party. They also make a fantastic photo backdrop!

We love this balloon arch for its simple color scheme (dark and light green, blue, orange) and various dinosaur balloons that pepper the arch. 

This particular arch would be perfect for both younger and older kids and would match several of the invitations listed above, including the Roaring T-Rex invitation and Roar! Roar! Roar! invitation. 


  • Reviewers appreciate the quality and endurance of the balloons

  • Foil dinosaurs are realistic and super cute!

The seller recommends you set aside about an hour to put this arch together, and you should use regular air, not helium.

  • Reviewers rave about color and quality


  • Process to put together a balloon arch can be frustrating. We recommend watching YouTube videos beforehand and giving yourself plenty of time to assemble it before the party!

4. Personalized Dinosaur Birthday Party Sign

The image displays a playful birthday sign or card set on a wooden easel, surrounded by a bunch of helium balloons in white and metallic green. The sign features illustrations of dinosaurs, including a T-Rex, a Stegosaurus, and a Pterodactyl among others, in a realistic yet soft art style, interspersed with green foliage. At the top of the sign, in a repeated pattern, the word "ROAR" is printed in a hand-written style font. The main text in a script font announces "Oliver is a THREE-REX!" playing on the word "T-Rex" to celebrate what is presumably Oliver's third birthday. The artwork has a modern, cheerful feel, using a neutral white background that makes the green text and dinosaur illustrations stand out.

We love that you can choose from green or pink in terms of color, but do keep in mind that each item is hand-made to order and may look slightly different than pictured.

10. Dinosaur Cake and Cupcake Toppers

Any great party needs a cake and/or a cupcake topper(s)! We like to use the cake or cupcakes as a centerpiece for the table when possible so that you don’t have to spend extra money on table decorations. 

Thinking of making your own cake? Try these fun dino sprinkles (with no artificial dyes!) and add any of the following cake or cupcake toppers to your creation. 

Pro-tip:  you can always call your grocery store and have them make a plain cake or cupcakes and adorn it with one of these fun toppers!

Here are our favorites:

  • Meri Meri Dinosaur Kingdom Cake Topper–this set is beautiful and easy to assemble! It includes 5 dinosaurs and a crepe paper palm tree. If you want to go all out, Meri meri also makes matching dinosaur party hats for guests to wear and dino plates for the cake. This topper (and matching party gear) would work for an infant or bigger kid (ages 0-5).
  • Rainbow Cake Topper with Dino Eggs– this cartoon-like set is made of high quality soft clay (food grade) and is non-toxic. It includes a total of 16 pieces, with three clay dinos as the star. Don’t love that option? This one is a little more conventional and sweet. This topper would be best for an infant or toddler’s dinosaur-themed birthday party. 
  • Realistic Dinosaur Cupcake Toppers–these have a great range of realistic dinosaurs flanked by greenery. There are 35 per pack, so if you’re having a big party, this set would be great! These toppers would be best for an older child’s party (4+)

Dinosaur Party Food

Okay, so we all know that the real star of any list of dinosaur party ideas is the FOOD. The cake is fun, sure, but there are some really easy ways to give basic party food more prehistoric pizazz (my bad, I just had to).

Anyway, here are our favorite ways to enliven your dino party with easy food options your party-guests will love, but don’t forget little dinosaur place cards so you can write food descriptions (and allergens) on them! 

1. Dino Bones

So dino bones are just white-chocolate covered pretzels! You can buy them pre-made or make your own my melting white baking chocolate

If making your own, I suggest buying the long, rod-style pretzels to make some pretty-epic stegosaurus femurs. Roll them in the melted chocolate and dino sprinkles if you dare!

2. Rwarrr-termelon 

Want to provide a healthy option to balance out all the cake? Grab some dinosaur cookie cutters and use them on seedless watermelon! 

You’ll want to slice it medium thick before using the cookie cutters, but otherwise, this snack is super easy to make. You can also layer the watermelon with grapes and strawberries on skewer sticks.

Don’t feel like buying a cookie cutter? Cut the watermelon into triangles and call it Stegosaurus Spikes! Or put out green grapes and call them “dino eggs.” Now aren’t you the coolest parent ever?

Pro-tip: use the cookie cutter set to make brontosaurus-shaped sandwiches! 

3.  T-Rex Toenails

Alright, so this one sounds gross, but it’s actually pretty cute. Grab a bag or two of Bugles and throw them into a bowl. Use your handy-dandy place cards to label them “T-Rex Toenails” or “Dino Claws.” Fun!

Not into Bugles chips or toenails in general? Regular tortilla chips work as “Dino Scales” (and don’t forget the mild salsa!). 

4. Watering Hole

Every party needs a watering hole! Use your gallon-sized water dispenser for this. Bonus points if you have two. Label them cute names like “pterodactyl punch” or “fossil fuel.”

Make sure you don’t forget adorable cups with straws for your watering hole, or cute plastic cups guests can take home. Don’t want to go that fancy? Paper cups are fine! 

5. Dino Eggs

The best part about making “dino eggs” is that you don’t have to make them! Grab a box of donut holes from the grocery story or from your favorite donut spot. Bam. You’ve got dino eggs. 

Other classic dinosaur party food includes classic kiddo-friendly food items such as:

  • dino nuggets, 
  • cutting boards full of charcuterie (for the carnivores),
  • and crudité (for the herbivores). 

Remember, it doesn’t have to be expensive or time-consuming to make! You just need a little forethought and creativity.
