Taking teeth to the extreme! Tusks have evolved numerous times, particularly in mammals, and they’ve come in a striking array of shapes and sizes for a variety of uses. From the monstrously huge ivory tusks of mammoths to the modest yet effective tusks of fanged deer to the bizarre and perplexing tusks of babirusas and narwhals, in this episode we discuss trends, drivers, and mysteries in the evolution of tusks.
In the news: razor-toothed mosasaurs, walk the dinosaur, sidewinder skin, and really old giant sloths.
