No sooner had Cutter and Connor gotten back from the trip, then Phillip had called and had wanted Connor back in the lab so it was just Cutter standing in front of the class that day, “welcome back,” he began, “this week we’re going to be talking about Inverterbrete Fossils, which are animals without backbones and they boast a fossil record covering a span of 600 million years and are a prime example of how their abundance, diversity, and wide range of adaptations make them an ideal resource for scientists to use in understanding how our planet has changed over time. Palaeontologists study fossils earn about these extinct animals and how they are related to modern animals and through this can learn  about the history of biodiversity, evolution, extinction events, climate changes, and paleobiogeography,” he explained.

Common kinds of invertebrate fossils include molluscs (snails), arthropods (trilobites), echinoderms and cnidarians (corals), These are all animals that, throughout most of Earth’s geological history, lived in a multitude of habitats including marine, freshwater, and terrestrial. Fossils are any trace of a previously living organism, and although invertebrates do not have “true” bones, they leave behind evidence of their past in the form of shells, molds and casts, track ways, fecal pellets, tubes, and exoskeletons.”

“For the rest of today’s class I would like you to work on the moddable worksheets that have been left out for you and as always if there’s any questions, I will be happy to answer them,”
