Topics:

  1. Discovery of a carnivorous dinosaur
  2. Definition of theropod (carnivorous, bipedal dinosaur)
  3. Correlation between human and dinosaur skeletons

Panel Summary:

Last expedition, the exposed edge of a hip bone was the initial clue that led the team to uncover more of the skeleton of a new theropod - Afrovenator, meaning “African hunter.”  The skeleton is 30 feet long.  Bones of plant-eating sauropods were found at the site of the Afrovenator skeleton, providing good evidence that they lived at the same time in the same environments (predator and prey).

Teacher’s Directions:

Make sure the students see the parallel between the bones of a human skeleton and that of the included dinosaurs.  If this is difficult for students to grasp, direct one student to GET DOWN ON ALL FOURS, and it will be more apparent!

The Predator

They stopped and stared.  Only the edge of one hip bone and claw were exposed at the surface.  The team immediately recognized the characteristic shape of these bones- they belonged to a predatory dinosaur.  Everyone was wondering how much of the animal lay beneath the surface.

With each passing day, the team found more bones.  Unlike those of the sauropod, the bones of the theropod were scattered around the site and were located within inches of the surface.  The team soon realized they had found bones from all parts of the skeleton included the skull.  It was the most important find of the field season - a new theropod!

Theropods are bipedal (two-legged), carnivorous (meat-eating) dinosaurs.  Their short, strong front limbs are adapted for grasping and tearing flesh.  Their three-toed limbs are built for running.  The long tail is used for balance and the narrow skull has rows of long curved teeth for holding onto live prey.

The team named the new theropod from Niger Afrovenator, meaning “African hunter.”  Afrovenator has a particularly long skull (more than 2 feet long) and a lightly-built skeleton about 30 feet long.  The long hind limbs indicate that Afrovenator was a particularly fast predator.  Sauropod bones were found close to the Afrovenator site, and it is very likely that Afrovenator preyed upon the large plant-eating sauropods.

A Skeletal Plan

Background

Did you know that you can match almost all the bones in your skeleton with those in a dinosaur skeleton?

Humans and dinosaurs belong to a large group of animals called vertebrates, all of which have bones that follow a similar skeletal plan.  The vertebrate skeletal plan evolved long ago (about 350 million years ago) in the ancestors of the vertebrates and was inherited by all of their descendants.

Vertebrate Skeletal Plan

Main Parts  Characteristics
Skull contains brain, jaws, and teeth
Vertebrae bones that form the backbone
Shoulder blade and pelvic girdle plate-shaped bones for limb attachment
Paired front and hind limbs
Each limb has 3 long bones
Front limb: humerus, radius, ulna                    

Hind limb: femur, tibia, fibula

Directions:

Study the labeled diagram of the human skeleton (next page).  Learn the names of the major bones.

1.  The bones in a skeleton of a sauropod dinosaur (following pages) are labeled with letters.   Name each bone next to the same letter listed below (use the technical bone names).  (HINT:  look for the same bones in the human skeleton)

A_______________

B_______________
C_______________

D_______________

E_______________

F_______________

2.  List the bones that are missing in the skeleton of Afrovenator.

Human Skeleton:

Many bones have two names, a technical name for the bone (“femur”), and a name that refers to the body part that contains the bone (“thigh bone”).

Teacher’s Answer Key:
