• The collision of micro-continents, islandarc terranes, or proto-continents into
Proto-North America has happened many
times over geologic history creating the

• Subsequent glaciations & glacial

Dinosaur
State Park
32
DINOSAUR STATE PARK
• Park has one of the largest on-site displays of dinosaur tracks in the world
• Beneath the geodesic dome is an exceptional display of early Jurassic fossil
tracks that were made 200 million years ago
• 500 tracks are enclosed within a 55,000-square-foot dome; the remaining 1,500
tracks are buried for preservation
• The trackway is located in Rocky Hill, CT (20 min south of Hartford)and has been
designated a registered Natural Landmark by the U. S. Department of Interior
33
DINOSAUR STATE PARK
• Most scientists agree thatLife
theForm Evolutionary Time Line
trackmaker was a carnivorous
dinosaur similar in size and shape to
Dilophosaurus. The tracks range from
10 to 16 inches in length and are
spaced 3.5 to 4.5 feet apart
• Dipolarsours was only about 9 ft tall,
20 ft long and weighed ½ ton
• Analysis of it’s teeth indicate poor
basal strength, therefore it’s assumed
that this dinosaur feed on dead
carcasses
• Time of dinosaurs started in the
Jurassic (200 mya) and lasted for 140
mya
34
DINOSAUR STATE PARK
• Trackway is only a
ONE INCH thick layer
of sandstone
• Tracks indicated that
dinos were traveling
alone and in different,
straight line

Rhode Island
Slater Mill
42
Rhode Island – Slater Mill
• Born in Derbyshire, England in 1768
• Known as the "Father of the American
Industrial Revolution" or the
• "Father of the American Factory System"
The story starts with…
• Learned textile machinery as an apprentice
to a pioneer in the British industry
• Brought his knowledge to America where
he designed the first textile mills
• Hannah Slater invented a type of cotton
sewing thread, becoming in 1793 the first
American woman to be granted a patent
Samuel Slater
(June 9, 1768 – April 21, 1835)
43
• By the end of Slater's life he owned
thirteen spinning mills and had established
tenant farms and towns around his textile
mills
• Price: He was considered a traitor in his
native England
Rhode Island – Slater Mill
• Drew on his British village experience to
create a factory setting based on
customary patterns of family life in New
England villages
• Children aged 7 to 12 were the first
employees of the mill starting in 1790.
• Tried to staff his mill with women and
children from far away, without avail due
to the close-knit framework of the New
England family
• Brought in whole families, creating entire
towns
• Provided company-owned housing nearby,
along with company stores and sponsored
a Sunday School where college students
taught the children reading and writing.
44
• This factory system is now called the
"Rhode Island System"

Today, the sea and land are

But,
IMAGINE A TIME
23,000 YEARS AGO
• Winter and it’s snows start
lasting a lot longer; snows
accumulate; glaciers advance
Atlantic Ocean
57
• Water levels fall & are 400 ft
lower than today; the ocean is
far from where Cape Cod WILL
BE
CAPE COD FORMATION
(lite green represents the
Advancing Glacier)
• Maximum
glacial advance
23,000 ybp
• Large glacial
debris pushed
forward by
different glacial
lobes
Martha’s
Vineyard
Island
58
Nantucket
Island
• Glacial debris
forms the future
islands of
Martha’s
Vineyard to the
west and
Nantucket to
the East
CAPE COD FORMATION
(lite green represents the
Advancing Glacier)
• By 19,000 ybp, the glacial ice
sheet has retreated to the
position of Cape Cod
• Additional glacial debris is
deposited to form Cape Cod
• Glacial outwash further
develops the bulk of the Cape
• Periodic advance and
retreating of the glacier
continues to add mass to the
Cape
• The ocean has not risen
sufficiently to erode the two
islands recently formed

CAPE COD FORMATION

CAPE COD FORMATION
KETTLE FORMATION
Kettle Ponds are
depressions caused
by
• chunks of ice
breaking off from
the glacier and
• slowly melting
away
• while water eroded
the soils under the
ice block
• Leaving a small
pond behind
