Dinosaur Day: When Is It Celebrated and What’s the History Behind It?

In the United States and many other countries, Dinosaur Day is celebrated on the third Tuesday of May. In addition, June 1 is recognized as National Dinosaur Day at the San Antonio Zoo in Texas.

But why do we dedicate an entire day to these ancient creatures? 

The History of Dinosaur Day

People first discovered evidence of dinosaurs back in 1677 — though at the time, a single fossilized bone was mistakenly believed to be from a giant human. 

In the early 19th century, scientists began finding more bones and teeth. These discoveries led to the idea that prehistoric animals once roamed the Earth — long before humans. 

Some of the dinosaur names we know today were invented during that time. For example, Iguanodon got its name because of its similarities to an iguana. 

It’s not entirely clear when Dinosaur Day first began in the U.S. or worldwide. But today, it’s a fun and educational holiday — especially for families with curious kids who love to explore the natural world.

How to Celebrate Dinosaur Day

The best way to celebrate? Dive into the world of dinosaurs! Below a few fun ideas for your family. 

Watch dinosaur-themed movies together, such as:

  • Jurassic Park
  • The Lost World
  • Night at the Museum

Play dinosaur board games or card games — they’re not only fun but educational too! 

Host a family quiz to find out who knows the most about dinosaurs.

Draw your own dinosaurs! Use your imagination to come up with what they might have looked like.

Visit a natural history museum where you can see dinosaur skeletons and other fossils in real life. 

However you choose to spend the day, make sure you have fun and learn something new!

Why Celebrate Dinosaur Day?

Dinosaur Day is a unique opportunity for both kids and adults to explore the history of life on Earth. 

Studying dinosaurs isn’t just about fossils — it’s also a great introduction to geology, geography, and climate science. You’ll learn about how Earth has changed over millions of years, how continents moved, and how the environment evolved. 

Most kids are fascinated by dinosaurs — and they’ll happily spend hours learning about them. That’s why this holiday is both fun and meaningful. 

At Palme School, we believe that topics children love — like dinosaurs — are powerful tools for learning. We build lessons around these interests to spark curiosity and make learning joyful.

If you want your child to explore science and language in a creative, engaging way, we invite you to get to know our school.

Ordinal numerals in Russian are formed by taking the root of the cardinal numeral and adding the appropriate ordinal suffix. These suffixes agree in gender, number, and case with the noun they modify. Here's a breakdown: **1. Basic Structure:** * **Cardinal Numeral + Ordinal Suffix** **2. Ordinal Suffixes:** The suffixes are generally based on the endings of adjectives. * **Masculine:** -ый (e.g., первый - first) * **Feminine:** -ая (e.g., первая - first) * **Neuter:** -ое (e.g., первое - first) * **Plural:** -ые (e.g., первые - first) **3. Examples:** Let's look at the first few numbers: * **Один (one):** * Masculine: первый (pervyy) * Feminine: первая (pervaya) * Neuter: первое (pervoye) * Plural: первые (pervyye) * **Два (two):** * Masculine: второй (vtoroy) * Feminine: вторая (vtoraya) * Neuter: второе (vtoroye) * Plural: вторые (vtoryye) * **Три (three):** * Masculine: третий (tretiy) * Feminine: третья (tret'ya) * Neuter: третье (tret'ye) * Plural: третьи (tret'i) * **Четыре (four):** * Masculine: четвёртый (chetvyortyy) * Feminine: четвёртая (chetvyortaya) * Neuter: четвёртое (chetvyortoye) * Plural: четвёртые (chetvyortyye) **4. Numbers 5 and above:** For numbers five and higher, the formation is more straightforward. You take the root of the cardinal numeral and add the standard adjectival endings. * **Пять (five):** * Masculine: пятый (pyatyy) * Feminine: пятая (pyataya) * Neuter: пятое (pyatoye) * Plural: пятые (pyatyye) * **Десять (ten):** * Masculine: десятый (desyatyy) * Feminine: десятая (desyataya) * Neuter: десятое (desyatoye) * Plural: десятые (desjatyye) * **Сто (one hundred):** * Masculine: сотый (sotyy) * Feminine: сотая (sotaya) * Neuter: сотое (sotoye) * Plural: сотые (sotyye) **5. Compound Numbers:** When forming ordinal numerals for compound numbers (e.g., twenty-first), only the last part of the cardinal number changes to an ordinal. * **Двадцать один (twenty-one):** * Masculine: двадцать первый (dvadtsat' pervyy) * Feminine: двадцать первая (dvadtsat' pervaya) * **Сто двадцать три (one hundred twenty-three):** * Masculine: сто двадцать третий (sto dvadtsat' tretiy) * Feminine: сто двадцать третья (sto dvadtsat' tret'ya) **6. Pronunciation and Spelling Changes:** You might notice some spelling and pronunciation shifts, especially with the softer vowels and consonant changes in the first few numbers. These are typical sound changes in Russian. **7. Case Agreement:** Like all adjectives, ordinal numerals must agree with the noun they modify in case. * **Nominative:** первая страница (the first page) * **Genitive:** первой страницы (of the first page) * **Dative:** первой странице (to the first page) * **Accusative:** первую страницу (the first page - direct object) * **Instrumental:** первой страницей (by the first page) * **Prepositional:** о первой странице (about the first page) **Key Takeaways:** * Ordinals are formed from cardinals with specific suffixes. * They agree in gender, number, and case with the noun. * The first few ordinals (первый, второй, третий) are irregular and have unique forms. * For compound numbers, only the last numeral becomes ordinal.
