  1. Challenge Day By Isabelle Laxamana

  2. How Fossils Are Formed • Firstly, I learned that fossils are formed when layers of dirt go over the skeleton. • Also, the tyrannosaurus rex’s skeleton before were thought to stand upright but later studies show they actually stood semi upright and are lizard hipped-dinosaurs. • I had fun digging up fossils with a brush and matching them with moulds. We match the fossil with moulds so that we know who the fossil belongs to.

  3. What Palaeontologists Do • Next, I learned that Palaeontologists study dinosaurs which I find very interesting • They use explosives, spades and brushes to find fossils, but Palaeontologists need to be careful because fossils are delicate. • After they find fossils, Palaeontologists examine them and match them with dinosaurs.

  4. Acrostic Poem • After that, I have created an acrostic poem using the word PALAEONTOLOGIST. • We didn’t get to finish it because we ran out of time.

  5. Fossil Types • In addition, fossils could be classified in two types; mould and rock fossils. • The mould fossils are formed when the dinosaur makes print on the ground like a footprint. The print is buried but isn’t destroyed. When the fossil is found, the Palaeontologist covers the fossil with plastic to protect it. • The rock fossils are formed when the dinosaur’s bone is sunken into the rock and Palaeontologist opens the rock with a special tool and inside is the bone.

  6. Conclusion • I had a fun day and learned a lot about fossils and at the same time made new friends.
