New Kangaroo Relative Discovered in Australian Fossil Caves
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Australian scientists have discovered a completely new species of bettong and two new woylie subspecies through fossil analysis, expanding our understanding of marsupial diversity and providing crucial information for conservation efforts.
📈 One key stat: Woylies can move several tonnes of soil each year while foraging for mushrooms, making them vital ecosystem engineers in Australian landscapes.
💬 One key quote: “Our results split the critically endangered woylie into two living subspecies, which is very important for conservation when we’re considering breeding and translocation initiatives to increase the size and fitness of populations.”
1️⃣ The big picture: Australian researchers have uncovered remarkable new diversity among kangaroo relatives through detailed fossil analysis. A team from Curtin University, Western Australian Museum and Murdoch University identified both a completely new bettong species and two previously unrecognized woylie subspecies from cave fossils across Western Australia. Though these discoveries expand our understanding of Australia’s marsupial diversity, the findings come with a bittersweet realization that some of these newly identified animals may already be extinct. Woylies play a crucial ecological role as ‘ecosystem engineers’ by moving tonnes of soil annually while foraging for mushrooms.
2️⃣ Why is this good news: This discovery significantly expands our knowledge of marsupial diversity in Australia, providing essential insights for conservation efforts focused on the critically endangered woylies. Recognizing two living subspecies creates new opportunities for targeted breeding programs that can increase population size and genetic fitness. The research demonstrates the value of examining fossils alongside genetic tools for conservation planning. Museum collections across multiple countries supported this research, highlighting the importance of preserving scientific specimens for future discoveries. This collaborative approach between multiple universities and museums showcases how institutional partnerships can advance our understanding of biodiversity.
3️⃣ What’s next: The scientific team will collaborate with Indigenous groups to develop an appropriate name for the new species, acknowledging the cultural significance of these animals. Conservation programs for woylies can now be refined to account for subspecies differences in breeding and translocation initiatives. Further research may reveal additional insights about these marsupials that could strengthen protection efforts for remaining populations.
