      Thanks for your question! During my first degree in Zoology, I was lucky enough to be part of a team at the University of Bristol who were investigating what colours dinosaurs were. I was able to help the researchers out with experiments for a couple of years alongside my degree. We extracted tiny little fossilised proteins from feathers and fossils called melanosomes. These melanosomes provide colourful pigments to different parts of the body…we find them in our skin and our hair (just like birds and other animals). Once we extracted these melanosomes from fossils (using chemical procedures), we then looked at the shape of the proteins under a very high-powered microscope called a Scanning Electron Microscope. By looking at the shape of the melanosomes, we could predict what colour that fossil or dinosaur was! Many dinosaurs had feathers and some were black and grey…but others were really brightly-coloured and had orange, red, and even iridescent feathers! It was a really amazing project to be part of. Here are a couple of fun videos to watch:

      Unfortunately I can’t answer this question as I’ve never worked in paleontology

      I cannot answer this question either since I have never worked in this area.

      I don’t work in palaeontology, but have used results of such work to answer questions associated with the geological disposal of radioactive waste.
      This may seem like a very strange link, but one of the worries we had involved deep disposal of radioactive waste solidified in resins. Many chemists thought that this was a silly idea, as such resins would degrade within hundreds or thousands of years. However, palaeontologists knew better and could prove this with examples of fantastically-preserved plants, insects and other animals fossilised in amber (which is a natural resin). Some examples – up to about 200 Million years old – can be seen here – https://eartharchives.org/articles/trapped-in-time-the-top-10-amber-fossils/index.html . If we can learn from nature and ensure such preservation, waste disposal can be demonstrated to be safe.
