Syllabus
WEEK 1
Bird Anatomy
In Lesson 1, we explore the anatomy and adaptations of birds, and
meet the Victorian scientists who first suspected the link between
the terrible lizards and modern birds. In order to fly, birds have
undergone a series of anatomical specializations that distinguishes
them from other vertebrates. However, many of the most striking and
anatomically unusual traits of birds originated over 230 million
years ago with the very first theropod dinosaurs. Just a quick note
before you get started: 'Palaios' is the Greek word for 'ancient',
so palaeontology or paleontology is the study of ancient life. Both
spellings are correct, with palaeontology used in Britain, and
paleontology more common in the US.

WEEK 2
Survey of Non-Avian Theropods
In the wake of the Permian mass extinction, the prehistoric world
was ripe for the taking. All the world’s landmass was consolidated
into the single supercontinent: Pangaea. With no seas standing in
their way, new terrestrial animal lineages were able to exploit new
habitats all across the globe. Archosaurs, meaning ‘ruling
reptiles’, came to dominate Triassic ecosystems. However,
dinosaurian archosaurs were not the top predators. Instead,
crurotarsans sat undisputed at the top of the food chain. The first
theropods were small, but agile carnivores, and although they
started out as the Darwinian equivalent of the mail room clerks, by
the next geological period (the Jurassic), they were large and in
charge. In Lesson 2, we will introduce you to some of the earliest
theropods, and explore the anatomical secrets to their survival and
eventual success. We will also meet the largest land predators of
all time.

WEEK 3
Coelurosaurs I
In the previous lesson, we explored how the various theropod
lineages adapted to their role as apex predators. In this lesson,
we will explore a new group of theropods, as much characterized by
their speed and agility as their predatory prowess. The
coelurosaurs were the most successful and diverse of all the
theropods, and included herbivores, the smallest of all dinosaurs,
and, of course, the mighty tyrannosaurs.

WEEK 4
Coelurosaurs II
Dinosaurs had long been thought of as overgrown reptiles; cold
blooded, swamp bound, with meagre intelligence and little to no
social complexity. The ‘Dinosaur Renaissance’ was a revolution in
palaeontological thinking that entirely transformed that
traditional image of dinosaurs. In Lesson 4, we will see how new
research and discoveries over the past fifty years have shaped our
modern image of dinosaurs into one of energetic, intelligent
animals, that likely displayed many of the complex social
behaviours witnessed in modern birds. You’ll also meet the
deinonychosaurs, A.K.A. ‘the raptors’, and you will learn the
leading theories for how one group of dinosaurs learned to fly.

WEEK 5
The Avian World
66 million years ago, an asteroid the larger than Mt. Everest
collided with the earth and brought about the extinction of the
dinosaurs…except birds! Now that you’re familiar with some of their
larger Mesozoic ancestors and their bird-like features, it’s time
to meet the avian lineage proper. With the evolution of flight,
birds could exploit habitats and resources that were literally
unreachable by other animals. The evolution of birds has been one
of diversification. Flightlessness has evolved numerous times, as
have specializations for insectivory, swimming, and predation.
Although theropods may no longer dominate the land, they still rule
the skies.
