Palaeontology and the history of life are topics that capture the imaginations of children and adults alike, many of whom are keen to learn all about the latest weird wonders discovered by science. Communicating cutting-edge research to the public can be difficult, however, partly because scientists tend to publish their results in technical papers aimed at other scientists, but also because these papers are generally not freely available to non-academics — although the growth of open access means that this is improving in many countries. Popular-science writers provide accurate and accessible summaries of some of the most topical work, but can cover only a fraction of the research carried out by palaeontologists, naturally focusing on current stories rather than the wealth of knowledge already out there. Moreover, misrepresentations of palaeontologists’ work are commonplace in the mainstream media, with research results often reported incorrectly, or lacking essential context. Taken together, all this hampers the public understanding of Earth history and contributes to the denial of evolution and climate change.
These issues were foremost in our thoughts when we set up Palaeontology [online] in 2011. The goal of the site is to publish monthly articles on palaeontology and related topics, written by experts, but understandable to secondary/high-school students and non-specialist adults. All of these articles are free to access, ensuring that anyone, anywhere in the world can read them whenever they want — all they need is an internet connection. The website, which is supported by the Palaeontological Association, officially launched to the public in July 2011 with an article by Alistair McGowan about biodiversity. Since then, we have published a total of 37 articles, which have been seen by more than 60,000 unique visitors from 179 countries (Fig. 1). To celebrate our three-year birthday, this month we take a quick look back at the articles that have helped to make the site the success it is today.As seems fitting given that palaeontology is the study of ancient life, a large number of our articles are focused on fossils — the preserved remains or traces of long-dead organisms (Fig. 2). This has included groups that most people have heard of, such as pterosaurs, marsupials, trilobites and apes, as well as much less familiar forms, including ancient animal embryos, tree-kangaroos, heterostracans and placodonts. The site has featured a range of articles about fossil arthropods — which is no surprise, given that the group encompasses the majority of all species alive today — notably arachnids (for example spiders and scorpions), pycnogonids (sea spiders), chasmataspids and xiphosurans (horseshoe crabs), all of which belong to a larger grouping called the chelicerates. There are also a number of articles covering broader topics, but with a particular focus on the fossil record, including coal swamps, vertebrate tracks, the preservation of colour, plants and past environments, animal development, concretions, dinosaur eggs and the interactions between arthropods and plants.
Of course, palaeontology isn’t just about fossils, and there are several articles dealing with large-scale patterns in Earth history (Fig. 3). These include the Paleocence–Eocene Thermal Maximum, the Cambrian explosion, the origin of life, body-size evolution and the latitudinal biodiversity gradient. In addition, there are contributions outlining the approaches and techniques used in modern palaeontology, such as the principle of parsimony, methods for collecting and analysing shape data, palaeoecology and the live–dead agreement, naming fossils and ancient DNA. Finally, there are articles about varied aspects of life as a palaeontologist, including career paths, the influence of the internet and open access, what is (and what isn’t) palaeontology and the history of the field.
Phew, I think that’s everything. As you can see, we’ve covered an awful lot in the past three years. Nevertheless, this is only the tip of the palaeontological iceberg, and with so many promising young researchers around, there will no doubt be plenty to write about for years to come. All that remains is to thank everyone who has contributed articles to the site and, in fact, everyone who has read the articles — thanks for your continued support, and here’s to many more years!
