Now that we've finished with the mammals for now, let's start building the area where is all started, the cartilaginous fish, the chondrichthyes.

Matilda's Lab turned 10 years old today.
To mark the occasion, I have updated the website's "About Matilda's Lab" page.
Also, the logo now sports an "Est. 2015", mainly because doing this any earlier would have looked a bit pathetic.

There's a new Matilda's Lab single on the loose!
The Waves is a tour through the electromagnetic spectrum but steering clear of the dangers of the high energy end of things.
It's available on the major streaming platforms. The link to my artist pages is here: linktr.ee/chrismacalis...

I completed this wave of updates to the mammals. I've actually gone slightly outside the scope of mammals. Adding Dimetrodon now makes this a map of the synapsids.

Here's a map of mammals update. I'm close to finishing this batch of mammals before moving to a different area of the map of life. I've added Deltatherium, who lived alongside the dinosaurs.

It's time for a map of life update. I've rounded off my illustrated placental mammals today, with that addition of 3 species within the Xenarthra: an armadillo, a sloth and an anteater.

The map of life's getting too big & complicated to keep updating the way that I have been, so I'm now working on the mammals section. I can then add it as a large element once I've included all of the mammals that I've drawn. So far, I've included the primates; 6 of them.
