Our new learning

Room 7 Dinosaur knowledge Prior Knowledge In 2 weeks, we learnt that... Animal Predator Dino is the root word ‘Saurs’ means something Species Extinct Huge Large bones Long necks Eggs Sharp teeth Long tails Eat people Different kinds Spikes Horns Mammals 4 legs Bipedal means 2 feet and quadruped means 4 feet. Some dinosaurs are bipedal and some are quadrupeds. Some can change between the two stances. They are sturdy. Theropod is a 3 clawed dinosaurs Dinosaurs are warm-blooded, which means their blood temperature is always the same Carnivore means a meat eater Herbivore means a plant eater Omnivore means it can eat plants and meat Some dinosaurs are huge and some are small. Typically, huge dinosaurs were sluggish (slow). Dinosaurs died out 66 million years ago. They started existed 230 million years. They died because of an extinction event, most people think this was because a meteor hit the Earth. Dinosaurs legs go out the bottom of their hip bones, whereas reptiles bones go to the side of their hips. Reptiles do not have an extra hole in their skull, but dinosaurs do. Mary Anning found lots of fossils on a cliffside in England in the 19th century. She was born in 1799 and died in 1847. She survived a lightning strike as a baby. In 1824 she found the first fossil. Non-avian dinosaurs are dinosaurs that are not birds. Avian means birds. Metabolism means how fast or slow your body converts food into energy Diverse means a big range Modifications means changes. Dinosaurs have modifications such as spikes, armour, horns or crests. Clade means family. Lineage means ancestors/descendants Paleontologists are scientists that study ancient things including dinosaurs There are 4 main groups of dinosaurs; theropods, sauropods, ankylosaurus and pterosaurs. Titanoboa was top of the food chain after the dinosaurs died. It killed people by constricting people. It spent most of its time in the water because it was super heavy. It was 13m long, as big as a bus. Hominis existed when 7-6 million years ago, the first humans to walk on 2 feet. People did not exist when dinosaurs existed. Adaptation is something that changes over time. Ecology - how animals relate to each other Fossils are made when dinosaurs die and their bones get trapped in rock or mud. The bones break down over time but leave a mould, which is filled with rock. This becomes the fossil. Dinosaurs sometimes eat each other. There were 3 periods of time that have dinosaurs. This is called the ‘age of dinosaurs’ also known as the ‘Mesozoic Era’; Triassic period, Jurassic period, and Cretaceous period. Then there were 3 more periods in time, “Age of mammals”, also known as ‘Cenozoic Era’; Paleogene Period, Neogene period and Quaternary period. Dinosaur fossils have been found on every continent, including Antarctica. Joan Wiffen found the first dinosaur fossil (a theropods tailbone) in NZ in 1975, in Hawkes Bay. She died in 2009. Dinosaurs laid eggs and they lived in family groups.

Joan Wiffen Joan wiffen was born on the 4th of february 1922.Joan wiffen died on the 30th of february 2009.Joan wiffen is famous because in 1957 she found the first fossil bone near Te Hao river.She found a theropods claw,Tail bone,Wing bone,another tailbone from an ankylosaur in manga hounga stream.

Matariki celebration

Martriki is a maori New year when families and whanaus come together for a big kai and  for big walks to welcome and thank the people that past away.Matariki are 7 sisters in the sky called you will see in the picture Above.Martiriki  is a time for people to get together and have fun.Martiriki is a time to get together and watch the stars.

The End i hope you enjoyed and learned something about matariki

compering the T-rex and the titanoboa

The T-rex was once the top of the food chain and the titanoboa was also once top of the food chain.They both are not vegetarians they are both carnivals.They are both now extinct/dead and they look very scary when they were alive.they were both very vicious and mean.

Lynch facts about the titanoboa

Where did it happen it happened in colombia.What did they find they found the titanoboa bone covered in rainforest it was covered in rainforest because it was very warm in colombia and the rainforest grow.One more cool fact is that when dinosaurs were alive the T-rex was the top of the food chain and when the dinosaurs died the titanoboa became the top of the food chain.The titanoboa went on land and in water the titanoboa went in the water the most because on land it is very hard for it to move because it is very harvey and in the water is very lite.

All About Fossils

Fossil


Fossils are dead animals or plants.They are usually skeletons found embedded in rock.sometimes fossils are footprints or poop.


Small animals or insects get stuck in tree sap which hardens and traps them forever.Large animals can get stuck in ice or their carcass gets trapped in layers of rock.Over thousands of years,pressure builds up and the skeleton is dissolved by water under the ground.Next the mould left is filled with minerals that from rock.This rock shape is the fossil - an exact replica of the dinosaurs.This process tacks 10,000 years.Palaeontologists find fossils when the top layers of dirt washes away.
