Question 1

How do you say micro-?

Accepted Answer

You say it MY-kroh, with the stress on the first syllable. The first part rhymes with 'my' as in 'my house,' and the second part sounds like 'crow' the bird. Put them together and you get MY-kroh. You almost certainly already say it correctly every time you say the word microphone or microwave.

Question 2

What does micro- mean in dinosaur names?

Accepted Answer

Micro- means small or tiny, and it comes from the Ancient Greek word 'mikros.' When paleontologists put micro- at the start of a dinosaur name, they are telling you the animal was unusually small compared to its relatives. It is one of the most honest prefixes in paleontology because it sets your expectations before you even look at the fossil.

Question 3

What dinosaurs have micro in their name?

Accepted Answer

The most famous is Microraptor, a four-winged gliding dinosaur from China that was smaller than a crow. Others include Microceratus, a tiny horned dinosaur from Mongolia, and Micropachycephalosaurus, which has the longest name of any known dinosaur despite being only about 50 centimeters long. All of them were named micro- because they were surprisingly small for their dinosaur group.

Question 4

How small was Microraptor?

Accepted Answer

Microraptor gui was about 77 centimeters long from snout to tail and weighed less than 1 kilogram, roughly the weight of a large apple. It is one of the smallest non-avian dinosaurs ever discovered. Despite its tiny size, fossil evidence shows it was an active predator that ate fish, small birds, and lizards.

Question 5

Is micro- Greek or Latin?

Accepted Answer

Micro- is Greek, not Latin. It comes from the Ancient Greek word 'mikros,' meaning small. Ancient Greek was widely used by early scientists and philosophers, and when modern science developed a formal naming system in the 1700s and 1800s, Greek roots like mikros were adopted because they were already familiar to educated people across Europe and beyond.

Question 6

Why do scientists use Greek and Latin to name dinosaurs?

Accepted Answer

Scientists use Greek and Latin because those languages are not tied to any one modern country, so a name agreed upon in 1850 means the same thing to a researcher in Brazil today as it does to one in China. It creates a universal scientific language. Greek roots like micro- are especially useful because they can be combined with other roots to build precise descriptive names.

Question 7

What is the longest dinosaur name and does it have micro in it?

Accepted Answer

Yes. Micropachycephalosaurus hongtuyanensis is the longest dinosaur name ever formally described, stretching to 23 letters in the genus name alone. It was a small dome-headed dinosaur discovered in China in 1978. Despite having such an enormous name, the actual dinosaur was only about 50 centimeters long, which makes the contrast between name length and body size pretty funny.

Question 8

What other science words use the prefix micro-?

Accepted Answer

Dozens of everyday science words use micro-, including microscope, microphone, microchip, microorganism, and microwave. In medicine there is microbiology and microsurgery. In physics there is the micrometer, which equals one millionth of a meter. All of them carry the same core meaning of very small that the Ancient Greeks captured in the word 'mikros' more than 2,000 years ago.

Question 9

Did Microraptor really have four wings?

Accepted Answer

Yes, Microraptor had feathers on both its arms and its legs, giving it four wing-like surfaces. Scientists described this in detail after analyzing fossils from Liaoning Province, China, formally published in the journal Nature in 2003. Most researchers think Microraptor used these four feathered limbs to glide between trees rather than to fly in a powered way like modern birds do.

Question 10

Why was Microceratus renamed?

Accepted Answer

The dinosaur was originally named Microceratops by paleontologist Otto Jaekel in 1953, but scientists later discovered that name already belonged to a genus of wasp that had been formally described back in 1933. Under international naming rules, the oldest name always wins, so the dinosaur had to be given a new name. It became Microceratus in 2008, keeping the micro- prefix but changing the rest to avoid the conflict.

Question 11

How do scientists pick names for new dinosaurs?

Accepted Answer

Scientists usually name dinosaurs after something distinctive about the animal, such as its size, a physical feature, where it was found, or who discovered it. They follow the International Code of Zoological Nomenclature, which sets rules for how names must be structured and published. Prefixes like micro- are popular because they instantly communicate key information and can be combined with other Greek or Latin roots to build new descriptive compound names.

Question 12

What does micro- mean in a microscope?

Accepted Answer

In the word microscope, micro- means small, and the second part comes from the Greek word 'skopein,' which means to look or to observe. So a microscope literally means an instrument for looking at small things. The word was coined in 1625 by Italian botanist Giovanni Faber, who used the same ancient Greek root that paleontologists later used to name tiny dinosaurs like Microraptor.
