skeleton, genetic, bones, 1854, 66, Hylaeosaurus, reptile, terrible, eagle, 19th, Megalosaurus, teeth, birds, talons, fossils, Iguanodon, mammals, Mesozoic, limbs, biology
•
paleontology
•
began as an organized study of knowledge in the          century
•
ways of studying dinosaurs
•
              
•
comes from the Latin fossilis which means "dug up" from fodere or "dig"
•
comparative               
•
uses natural variation and disparity to understand the patterns of life at all levels
•
               analysis
•
we still have thousands of species of dinosaurs living with us today, we just call them           
•
dinosaurs in the classical sense
•
lived in the                  Era, the "Age of the Reptiles"
•
252 to      million years ago
•
questions about dinosaurs
•
these four animals are all extinct but only the sauropod is a dinosaur
•
dimetrodon
•
sauropod
•
tiktaalik
•
mammoth
•
the word dinosaur means "                 lizard"
•
many people have the misconception that any extinct large reptile was a dinosaur, some people even think                such as wholly mammoths were dinosaurs
•
to a paleontologist, a dinosaur has very particular characteristics based on the                 , e.g.
•
air sinus
•
hind limbs are different, unique ankles
•
no other animals share this structure of legs, except, of course, their descendents, the birds
•
Sir Richard Owen
•
in          invented the term "dinosaur"
•
at that time, no complete dinosaur skeleton had been found
•
only a small number of fragments were known
•
jaw, hip from                         
•
teeth, vertebrae of an                   
•
ribs, shoulder, part of skull,                         
•
each of these three had been identified as a giant prehistoric               
•
Sir Richard Owen was the first to realize that all three shared an unusually combination of traits
•
they were more closely related to each other than to any living reptile
•
           that grew in sockets like crocodiles
•
erect            like mammals and birds
•
skeletons
•
almost everything we know of dinosaurs comes back to fossilized           
•
bones are made of minerals and so do not rot away as other bodily structures
•
in order to understand dinosaurs, you need to understand how dinosaur skeletons are put together
•
skeleton of an           
•
eagles, adaptations in evolution:
•
wings
•
large eyes
•
sharp             

Vocabulary:

synchrotron, n. a particular type of cyclic particle accelerator in which the guiding magnetic field, or bending of the particles into a closed path, is time-dependent, being synchronized to a particle beam of increasing kinetic energy ⇒ "Paleontologists use many tools, from hamers and chisels, to CT scanners and synchrotrons."
backronym, n. a specially constructed acronym created to fit the letters of an existing word ⇒ ""The name for the synchrotron facility near Paris SOLEIL is a backronym for 'Source optimisée de lumière d’énergie intermédiaire du LURE', where LURE means 'Laboratoire pour l'utilisation du rayonnement électromagnétique'""

People:

######################### (1804-1892)
English biologist, comparative anatomist and paleontologist who coined the word Dinosauria (meaning "Terrible Reptile" or "Fearfully Great Reptile")
  • Owen is also remembered for his outspoken opposition to Charles Darwin's theory of evolution by natural selection, althought agreeing with Darwin that evolution occurred, he thought it was more complex than outlined in Darwin's On the Origin of Species
  • Owen's driving ambition, occasionally vicious temperament, and determination to succeed meant that he was not always popular with his fellow scientists
  • known for his campaign for the natural specimens in the British Museum to be given a new home, by making the Natural History Museum an institution for everyone, Owen transformed our expectations of what museums are for
######################### (1790-1852)
English geologist and palaeontologist whose attempts to reconstruct the structure and life of Iguanodon began the scientific study of dinosaurs
  • 1822 he was responsible for the discovery and identification of the first fossil teeth and later the full skeleton of an Iguanodon

Spelling Corrections:

comparitive ⇒ comparative
