Question 1

How do you say caudo-?

Accepted Answer

You say it KAW-doe, with the stress on the first syllable. The first part rhymes with the word caw, like the sound a crow makes. The second part sounds like the word doe, as in a female deer. Put them together and you get KAW-doe, clean and simple.

Question 2

What does caudo- mean?

Accepted Answer

Caudo- means tail, or relating to the tail end of something. It comes from the Latin word cauda, which Roman writers used over 2,000 years ago to describe the tails of animals. When you see caudo- at the start of a dinosaur name or an anatomy term, it is a signal that something about that creature's tail is being described or celebrated.

Question 3

What dinosaurs have caudo- in their name?

Accepted Answer

The most famous is Caudipteryx, a feathered dinosaur from China whose name means tail feather. It was described in 1998 and had a dramatic fan of display feathers at the tip of its tail. The prefix also appears in anatomical terms used for nearly every dinosaur ever described, since caudal vertebrae is the standard scientific term for tail bones.

Question 4

Is caudo- Latin or Greek?

Accepted Answer

Caudo- is Latin, not Greek. It comes from the classical Latin noun cauda, which means tail. Many dinosaur name roots are Greek, but caudo- is one of the clearly Latin ones. Scientists sometimes mix Latin and Greek roots in the same name, but caudo- itself is always traced back to Latin.

Question 5

What is a caudal vertebra?

Accepted Answer

A caudal vertebra is simply a tail bone. The word caudal means relating to the tail in Latin-based scientific language. Dinosaurs could have anywhere from a handful to over 80 caudal vertebrae depending on the species. Diplodocus, one of the longest sauropods, had around 80 tail bones that together formed a whip-like tail that may have cracked the sound barrier.

Question 6

What did Caudipteryx look like?

Accepted Answer

Caudipteryx was about the size of a turkey and walked on two legs. Its most striking feature was a fan of large, symmetrical feathers at the end of its tail, which is exactly what its name means. These feathers were useless for flying because they were too symmetrical, but they were probably used to attract mates or intimidate rivals, much like a peacock's tail works today. It was discovered in China and described in 1998.

Question 7

How long were dinosaur tails?

Accepted Answer

Dinosaur tails varied enormously by species. Small theropods like Velociraptor had stiff tails just a few feet long used for balance. Sauropods like Diplodocus had tails stretching over 40 feet, longer than a school bus. A 1997 study by scientists Nathan Myhrvold and Philip Currie calculated that the tip of a Diplodocus tail could move fast enough to break the sound barrier, producing a loud crack.

Question 8

What is the caudofemoralis muscle?

Accepted Answer

The caudofemoralis is a muscle that runs from the tail bones to the thigh bone, the femur, and it was one of the most important muscles for movement in non-avian dinosaurs. Research by scientist John Hutchinson showed it was likely the primary engine driving the powerful leg stroke of large theropods. In living crocodilians, which are close relatives of dinosaurs, this muscle is still enormous and provides much of their swimming and walking power.

Question 9

Do humans have anything called cauda?

Accepted Answer

Yes, humans have the cauda equina, which is Latin for horse's tail. It is a bundle of nerve roots at the bottom of the spinal cord that fans out and looks like a horse's tail. Doctors also use the word caudal to describe the direction toward your feet or the lower part of your body. When anesthesiologists do a caudal block to manage pain, they are injecting near the caudal, or lower tail-end, of the spine.

Question 10

Why do scientists use Latin words to name dinosaurs?

Accepted Answer

Scientists use Latin and Greek words because they are universal. A paleontologist in Japan and a paleontologist in Argentina both recognize caudo- as meaning tail, even though neither of them speaks Latin as a native language. The International Code of Zoological Nomenclature, first established in 1895, requires that species names be formed from Latin or Greek roots precisely so that scientists worldwide can communicate without confusion.

Question 11

What does cauda equina mean?

Accepted Answer

Cauda equina is Latin for horse's tail. It refers to the bundle of nerve roots at the very base of the human spinal cord, which fans out and genuinely resembles the tail of a horse when you look at it. Anatomists have used this name since at least the 17th century. Damage to the cauda equina is a serious medical emergency that can cause paralysis and loss of bladder control.

Question 12

Are there other science words that use caudo-?

Accepted Answer

Yes, many fields use caudo- or its root cauda. In fish biology, the caudal fin is the tail fin, and its shape tells scientists how a fish swims. In botany, the word caudex refers to a plant's persistent basal stem. Historically, astronomers used cauda to describe the tail of a comet. In medicine, caudal is a standard directional term used every day in surgeries and anatomy classes around the world.

Question 13

How do paleontologists count tail bones?

Accepted Answer

Counting caudal vertebrae is one of the first steps in describing a new dinosaur. Scientists carefully excavate and number each tail bone from the base of the hips outward toward the tip of the tail. The number of caudal vertebrae varies a lot between species and is actually useful for telling species apart. Diplodocus had around 80, while birds, which are living dinosaurs, have fused most of their tail bones into a single structure called the pygostyle.
