Mammoth

A mammoth is any species of

the extinct genus Mammuthus,

proboscideans commonly

equipped with

long, curved tusks and, in

northern species, a covering of

long hair.

Mastodon

Mastodons are an extinct group of

mammal species related

to elephants, that

inhabited North andCentral

America during the

late Miocene or late Pliocene up to

their extinction at the end of

the Pleistocene 10,000 to 11,000

years ago.Theirgenus name

is Mammut.

Saber-toothed cat

A saber-toothed cat also

misleadingly known as

a saber-toothed tiger, is

any of various groups of

predatory mammals related

to modern cats that were

characterized by

long, curved sabre-

shaped canine teeth.

Ground sloth

Ground sloths are a diverse

group of extinct sloths, in

the mammalian superorder Xe-

narthra. The term "ground

sloth" is used as a reference for

all extinct sloths because of the

large size of the earliest forms

discovered, as opposed to the

extant "tree sloths

First Hominids

Megalodon

Ramapithecus

Rhinos

Tapirs

The tapir is a

large browsing mammal,

similar in shape to a pig, with a

short, prehensile snout. Tapirs

inhabit jungle and forest regions

of South America, Central

America, and Southeast Asia.

Plesiadapiforms

• Plesiadapiformes is

an

extinct order of mamm

als. The earliest

Plesiadapiformes have

teeth that are strongly

indicative of a common

ancestor.

Marsupials

• Young are carried in

a pouch. Well-known

marsupials

include kangaroos, w

allabies, the koala, po

ssums, opossums,wo

mbats and

the Tasmanian devil.

K-T extinction

Pterosaurs

Pterosaurs were flying

reptiles existed from the

late Triassic to the end

of the Cretaceous

Period. Pterosaurs are

the earliest vertebrates

known to have evolved

powered flight.

Ammonites

Crocodilians

Sauropods

Archaeopteryx

• Archaeopteryx

Archaeopteryx is

credited as being

the earliest known

true bird.

Archaeopteryx had

fingers, claws, and

teeth like many of

the dinosaurs.

Cycads

Cycads

• Cycads are known as ‘living fossils’ because they have remained unchanged for millions of years.

Gingkos

Rush

Rush

• Any of several flowering plants distinguished by cylindrical stalks or hollow, stemlikeleaves. They are found in temperate regions and particularly in moist or shady locations

CROCODYLIFORMS

A clade of archosaurs the

group often traditionally

referred to as "crocodilians."

Crocodyliforms are the only

non-avian archosaurs to

have persisted through the

Mesozoic and Cenozoic into

modern times. With their

stark appearance, it is often

assumed that they have

changed little in 200 million

years of evolution.

ICHTHYOSAURS

LABYRINTHODONT

An extinct amphibian

subclass, which constituted

some of the dominant

animals of late Paleozoic

and early Mesozoic eras.

They were short-legged and

mostly large headed, with

moderately short to long

tails.

Conodonts

Pangea

Stoneflies

Caddisflies

Trilobites

Trilobites are

remarkable, hard-

shelled, segmented

creatures that

existed over 520

million years ago in

the Earth's ancient

seas.

Mayflies

Mayflies spend a year

awaiting their birth, and

then most die after

living just one day.

Their sole purpose is to

pass on their genes, and

most never even bother

eating and that's been

the status quo for 100

million years.

Foraminiferans

• Foraminiferans

(forams for short) are

single-

celled protists with

shells. Their shells are

also referred to

as tests because in

some forms the

protoplasm covers the

exterior of the shell.

BryozoansThe Bryozoa, also known as

Polyzoa, Ectoprocta or

commonly as moss animals,[5]

are a phylum of aquatic

invertebrate animals. Typically

about 0.5 millimetres

(0.020 in) long, they are filter

feeders that sieve food

particles out of the water using

a retractable lophophore, a

"crown" of tentacles lined with

cilia.

Branchiopods

• Each has two valves

(shell sections)

which cover the

dorsal and ventral

surface of the

animal.

Blastoids

Lycopsids

• Lycopsids are the

oldest group of

living vascular

plants.

Tetrapods

Ammonoids

Crinoids

Have lived in the world's oceans since at least the beginning of the Ordovician Period, roughly 490 million years ago. They may be even older.

Springtails

Have antennae, three

pairs of legs, a

segmented body

and can have

simple

mouthparts, mouth

parts, used to suck

fluids from fungi.

Uniramian

Group within the

arthropods. In the

past this group

included the

Onychophora, whic

h are now

considered a

separate category.

CooksoniaCooksonia is an

extinct grouping of

primitive land plants. [ Cooksonia includes

the oldest known

plant to have a stem

with vascular tissue

and is thus a

transitional form

between the primitive

non-vascular

bryophytes and the

vascular plants.

Graptolites• Graptolithina is a

class in the animal

phylum

Hemichordata, the

members of which are

known as graptolites.

Graptolites are fossil

colonial animals

known chiefly from the

Upper Cambrian

through the Lower

Carboniferous

(Mississippian).

Gastropods

The Gastropoda or

gastropods, more commonly

known as snails and slugs, are

a large taxonomic class within

the phylum Mollusca. The class

Gastropoda includes snails and

slugs of all kinds and all sizes

from microscopic to large. There

are many thousands of species

of sea snails and sea slugs, as

well as freshwater

snails, freshwater limpets, land

snails and land slugs.
