Question 1

How do you say Carnivory?

Accepted Answer

Carnivory is pronounced kar-NIV-or-ee, with the stress on the second syllable. Break it into four parts: kar, then NIV, then or, then ee, and say the NIV part the loudest. It rhymes roughly with 'car give or ee' if you say it quickly. Once you have it, it feels totally natural to say.

Question 2

What does Carnivory mean?

Accepted Answer

Carnivory means the practice of eating animal flesh or tissue to get nutrition and energy. It comes from two Latin words: caro meaning flesh and vorare meaning to devour. An animal that practices carnivory is called a carnivore. It covers both active hunting and scavenging, since both result in eating other animals.

Question 3

What is the difference between a carnivore and a predator?

Accepted Answer

A carnivore is any animal that eats meat, while a predator is specifically an animal that hunts and kills other animals. All predators are carnivores, but not all carnivores are predators. A vulture, for example, is a carnivore that mostly eats animals it did not kill itself, making it a scavenger rather than a predator. Many carnivorous dinosaurs were likely both, hunting when they could and scavenging when it was easier.

Question 4

Were most dinosaurs carnivores or herbivores?

Accepted Answer

Most dinosaurs were actually herbivores, not carnivores. Estimates suggest that carnivorous theropods made up a relatively small percentage of dinosaur diversity compared to the enormous variety of plant-eating sauropods, ornithopods, ceratopsians, and ankylosaurs. This is the same pattern we see in modern ecosystems, where plant-eaters vastly outnumber meat-eaters because plants are a more abundant energy source than other animals.

Question 5

What did carnivorous dinosaurs actually eat?

Accepted Answer

It depended entirely on the species and its size. Large carnivores like T. rex and Allosaurus hunted and ate other large dinosaurs such as hadrosaurs, sauropods, and ceratopsians. Medium-sized carnivores like Deinonychus likely preyed on smaller dinosaurs and mammals. Tiny carnivores like Microraptor ate fish, lizards, and small birds. Some large carnivores like Spinosaurus specialized almost entirely in fish, based on isotope evidence from their teeth.

Question 6

How do scientists know a dinosaur was a carnivore?

Accepted Answer

Scientists use several types of evidence. The clearest clue is tooth shape, as carnivorous dinosaurs almost always have pointed, blade-like, serrated teeth very different from the flat grinding teeth of plant-eaters. Bite marks on other dinosaur bones, fossilized dung containing bone fragments, and even preserved stomach contents have all been used to confirm specific carnivorous dinosaurs. Chemical isotope analysis of fossilized teeth can also reveal where an animal sat in the food chain.

Question 7

What is the biggest carnivorous dinosaur ever found?

Accepted Answer

The title is contested, but the strongest candidates are Spinosaurus, estimated at 46 to 59 feet long, and Tyrannosaurus rex, Giganotosaurus, and Carcharodontosaurus, all of which reached lengths of around 40 to 43 feet. Spinosaurus is currently considered the longest, but its unusual build and fish-focused diet make comparisons tricky. T. rex is generally considered the most powerful in terms of bite force and overall body mass relative to its length.

Question 8

Did T. rex hunt or just scavenge?

Accepted Answer

The evidence strongly supports that T. rex was an active predator that also scavenged when the opportunity arose, just like lions and hyenas do today. Healed bite marks found on the tail vertebrae of a living Edmontosaurus show that the prey animal survived a T. rex attack and lived long enough for the bone to regrow, which is definitive proof of active predation. Most paleontologists today agree it was primarily a predator but was certainly not above eating an already-dead meal.

Question 9

Are there any carnivorous plants that count as practicing carnivory?

Accepted Answer

Yes, absolutely. Carnivory as a biological term applies to plants as well as animals. Venus flytraps, pitcher plants, sundews, and over 600 other plant species trap and digest insects and small animals to supplement nutrients that are scarce in their environments. The digestion process involves enzymes very similar in function to those used by animal carnivores. Botanists officially classify these plants as carnivorous under the same scientific framework.

Question 10

What adaptations do carnivorous dinosaurs have that herbivores don't?

Accepted Answer

Carnivorous dinosaurs typically have sharply pointed and serrated teeth for piercing and slicing flesh, while herbivores have blunt or ridged teeth for grinding plants. Many carnivores have forward-facing eyes that give better depth perception for judging distances when chasing prey. Strong gripping claws or enlarged hand claws are common in carnivorous theropods, used to seize struggling animals. Their digestive systems were also shorter and more acidic, suited to breaking down protein rather than tough plant cellulose.

Question 11

Can birds be considered carnivores since they evolved from dinosaurs?

Accepted Answer

Many birds absolutely are carnivores, and they are in fact living dinosaurs descended from small feathered theropods. Eagles, hawks, owls, herons, kingfishers, and even shrikes are dedicated carnivores that hunt fish, mammals, reptiles, and other birds. Some birds like vultures are carnivorous scavengers. The carnivorous behavior seen in these modern birds is a direct continuation of feeding strategies that evolved in non-avian dinosaurs over 200 million years ago.

Question 12

What is a hypercarnivore?

Accepted Answer

A hypercarnivore is an animal whose diet consists of more than 70 percent animal flesh, as opposed to a mesocarnivore which eats a more mixed diet. T. rex and Velociraptor would be classified as hypercarnivores. The term helps scientists be more precise when describing carnivory because some animals like bears and raccoons eat meat but also eat large amounts of plant material, making them very different ecologically from dedicated meat-eaters.

Question 13

Did small carnivorous dinosaurs hunt in packs?

Accepted Answer

This idea became popular after the movie Jurassic Park, but the evidence is actually quite weak. The main evidence sometimes cited for pack hunting in Deinonychus comes from sites where multiple individuals were found near large prey, but some paleontologists now argue those individuals may have been killed by the prey or were scavenging rather than cooperating. True coordinated pack hunting is extremely difficult to prove from fossils alone, and many researchers are skeptical it occurred in most small carnivorous dinosaurs.
