    It’s Albert the Albanerpetontid! Further reading: Earliest example of a rapid-fire tongue found in ‘weird and wonderful’ extinct amphibians Amphibian skullllll: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Let’s learn about a long-extinct amphibian that looked a lot like a reptile. It’s a family of animals called Albanerpetontidae. That’s a mouthful, so instead of talking about Albanerpetontids, I’ll talk about all the various species as though they were not only a single species, but a single individual named Albert. Albert first appears in the middle Jurassic, around 165 million years ago, and disappears from the fossil record around 2 million years ago. That means it survived the extinction event that killed off the non-avian dinosaurs and many other animals, which is also true for many other amphibians. But Albert wasn’t like the amphibians we have around today. It belonged to its own order, Allocaudata. There’s a lot of confusion in general as to how amphibians are related to each other and how closely related, for instance, the frogs and the salamanders actually are. The same is true for Albert. What we do know is that Albert was definitely an amphibian, but it was also really different in many respects from modern amphibians. That’s weird, because only two million years ago Albert was still around and seems to have been fairly common. Albert fossils have been found in Europe, North America, northern Africa, and parts of Asia. Two million years isn’t all that long when you’re talking about big differences between related animal groups. But although Albert appears in the fossil record at about the same time as other amphibians, it seems to have evolved very differently in many ways. Albert looked like a salamander and was originally classified as a salamander. It was small, its body was slender and elongated, its legs were short, and it had a long tail. It had tiny teeth and seemed to prefer wet environments, which makes sense when you’re talking about an amphibian. But Albert had a lot of traits not found in other amphibians, such as scales. The scales were more fish-like than reptilian and were embedded in Albert’s skin like osteoderms, especially concentrated on the head. These scales have caused confusion for a whole lot of scientists. In 2016, for instance, scientists identified an unusual lizard found fossilized in amber as a 99-million-year-old chameleon. That’s because it had a weird bone in its jaw shaped like a little rod, which looked like a bone found in the modern chameleon’s tongue. It turns out that the lizard was no lizard at all but our friend Albert, an amphibian. The chameleon is a reptile and not related to Albert, but they share the same type of elongated tongue bone. When the skull of a second amber specimen was discovered that was even better preserved, including a tongue pad and other soft tissue, scientists were able to evaluate whether Albert used its tongue the same way that a chameleon does. One trait found in Albert skulls that scientists had long been confused about was how robust and large its skull was. Some scientists suggested that it used its big head to dig burrows, ramming its head into soft mud until it created a hole big enough to hide in. But it also had big eyes, which isn’t typical in an animal that burrows. Scientists now think that Albert’s head was so strong because it needed to withstand the forces of its own tongue. It could probably shoot its tongue out incredibly fast like a chameleon, much faster even than a frog. It’s referred to as a projectile tongue, ballistic tongue, rapid-fire tongue, or boomerang tongue. The muscles that power a chameleon’s tongue are specialized to store energy when it contracts, then launch the tongue out like someone releasing a stretched-out rubber band. Albert’s similar ability evolved separately from the chameleon’s, and much earlier. It’s also possible that Albert didn’t undergo a larval stage the way most other amphibians do. Juvenile specimens look like miniature adults, which is unusual in amphibians but ordinary in reptiles. Albert also had lizard-like claws. But we know Albert wasn’t a reptile, and in fact it may have demonstrated one of the most amphibian traits known, breathing through its skin. Many modern salamanders don’t have lungs or gills at all as adults, and instead absorb oxygen directly through the skin, called cutaneous respiration. The specialized bone in Albert’s jaw would have made it hard to breathe in the ordinary way, and we know it didn’t have gills. The big question is why Albert went extinct when other amphibians are doing just fine. We don’t have an answer for that, or not yet. While Albert did seem to be quite successful, fossils of tiny, delicate animals like two-centimeter-long amphibians are rare, and that means we don’t have the full picture of what happened two million years ago that drove...

    Episode 476 Hercynian Animals

    Further reading: Identifying the beasts in Caesar’s forest Reindeer: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. After the glaciers retreated from Europe at the end of the last ice age, around 11,000 years ago, forests grew wherever there was enough soil to support a tree. As these new forests spread, they joined forests that had survived the glaciations. By the time ancient Romans were writing about the things they encountered while exploring western Europe, around 2,000 years ago, the forest stretched across much of the continent and was considered a wild, dangerous place. They called it the Hercynian [her-SIN-ian] forest and it was supposed to be full of peculiar animals. An account of the forest appears in the book Commentarii del Bello Gallico, the first edition of which was published just over 2,000 years ago in 49 BCE. It was written by Julius Caesar, or at least he was involved in it even if he didn’t actually write it personally, since it was about his military campaigns. In one section of the book he discusses the Hercynian forest and three remarkable animals that lived in it. The first was called the uri, which were supposed to look like bulls but were almost the size of elephants, and were incredibly aggressive. This is probably the same animal often called the aurochs, which we talked about in episode 58. The aurochs was probably the wild ancestor of the domesticated cow and could stand almost six feet tall at the shoulder, or 1.8 meters. It had already gone extinct in most places 500 years before Caesar wrote his book, but it still lived in parts of Europe. The second animal is a lot harder to identify. The alces looked like a big goat that either didn’t have horns or had very short ones, but its legs didn’t have joints. If an alces fell over, it couldn’t get up again. Caesar explained that hunters used this to their advantage. Because the alces couldn’t lie down at night, it would sleep by propping itself against a tree. The hunters would note which tree an alces preferred, and during the day they’d cut a notch in the trunk. When the alces leaned against it at night to sleep, the tree would topple over, taking the animal with it. The waiting hunters would then be able to just stroll up and kill the alces. Naturally, this story doesn’t make any sense. All tetrapods have jointed legs. But the story of an animal without joints in its legs crops up in various stories from around this time, including the part where hunters cut a notch in a tree trunk to knock the animal over. It’s a story once told about the elephant and the Eurasian elk, among others, and the alces was probably based on the Eurasian elk. That’s the Eurasian population of the animal called the moose in North America. Because the story specifies that the alces either didn’t have horns or had very small ones, it’s possible that Caesar based his story on the female elk, which doesn’t have antlers. Incidentally, we’re so certain that the alces was the same animal as the Eurasian elk that its scientific name is actually Alces alces. Finally, the Hercynian deer was likewise large and had a single horn. A translation of the passage states: “There is an ox with the shape of a deer; projecting out of its forehead, in the middle, between the ears, is a single horn, which is both longer and more upright than those horns we are used to seeing.” Other sources that talk about this animal also say that the horn branched at the end, and Caesar notes that both males and females had these horns. This gives us a big clue as to what animal might have inspired the account. Unlike most deer, both male and female reindeer have antlers. Unlike caribou, the North American reindeer species, the European reindeer often has relatively long and straight main shafts on its antlers that then enlarge at the end in what’s called a palmate structure. That basically means it’s shaped like a hand. But reindeer have two antlers, not one. It’s possible that the story of the Hercynian deer was inspired by the unicorn legend, which was based on the rhinoceros. It might also have been inspired by Caesar sighting a reindeer that had dropped one antler but hadn’t yet lost the other one, since like other deer, reindeer shed their antlers and regrow them every year. The reason Caesar wrote about the animals of the Hercynian forest in the first place was to underline how strange and uncivilized the people living in the area were. The people in question are what today we would call Germans. Caesar stresses that all these animals are ones never seen anywhere else, and he might easily have added exotic details from other fabulous animals to make these animals seem extra weird. These days most of the Hercynian forest is long gone, chopped down for people to turn into farmland and towns. While the Eurasian elk and the reindeer are still around, they no longer live as far south as Germany. The last ...

    Episode 475 Superweb

    This week let’s look at the work of a really astonishing number of spiders! Further reading: Megaweb! Some of the webs: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. Baltimore, Maryland is a city in the northeastern United States, in North America, with a population of 2.8 million people. In 1993 a new wastewater treatment plant was built called the Back River Wastewater Treatment Plant, which filters water through big sand beds to trap any particles remaining in it after it’s been filtered and treated in other facilities. The plant consists of 48 big sand beds with a corridor down the middle, and in order to keep the sand beds as clean as possible, the whole area has a big metal roof over it held up with steel columns. It doesn’t have walls, though, just a roof. The whole thing covers four acres, or 1.6 hectares, which I think is a metric term. It’s just over 16,000 square meters. It’s big, in other words, and the roof is pretty tall, up to 24 feet high over the walkway, or 7.5 meters. Obviously, I’m telling you about this place in detail because of an animal that got into the water treatment plant and caused a lot of alarm. It wasn’t a big animal like a bear, though. It wasn’t even a dangerous animal. It was, in fact, a really small animal that’s mostly harmless to humans, various species of orbweaver spider. The problem wasn’t the spider itself but just how many spiders were in the water treatment plant. The plant had always had problems with lots of orbweavers, but in 2009 there were so many spiders that the workers were worried for their safety. In late October 2009, the managers called for help about “an extreme spider situation.” The problem was way beyond anything that an ordinary pest control business could deal with, so the city put together a team of arachnologists, entomologists, and experts in urban pest control to figure out the best course of action. The team didn’t just charge in, say, “Wow, that’s a lot of spiders, let’s hose the whole place down.” They were scientists and studied the situation methodically. They consulted the architectural plans of the plant to determine just how much volume was available under the roof, they took samples of the webs and stored them for study, they took over 300 photos, and basically they got as much data as they could. There were so many spiders that their webs blended together into thick mats that filled almost every space the spiders could reach. These cobweb mats were attached to the rafters, the walkways, everywhere, with the older mats starting to detach and fray. Light fixtures hung down from the tallest point of the roof that were 8 feet long, or 2.44 meters, and there were so many webs attached to them that they were pulled out of alignment. And all the webs were filled with spiders. The spiders in the web samples were removed and preserved, then examined to see what species they belonged to. The team identified specimens from nine genera in six families, but most of the spiders caught were the species Tetragnatha guatemalensis. This is a type of long-jawed orbweaver native to North and Central America. Females are much larger than males, with a legspan up to 2 inches across, or about 5 cm. Long-jawed orbweavers have long, thin bodies, and one of the ways it hides is by stretching out on a blade of grass or a twig with its legs out straight. It especially likes marshy areas, such as in the rafters above 48 giant sand beds full of water. A conservative estimate of the number of spiders in the Back River Wastewater Treatment Plant in the first week of November, 2009 was 107 million. 107 million spiders! Since a big percentage of the spiders were newly hatched, there were probably a lot more in the facility than the scientists estimated from the samples they took, so there might easily have been several hundred million spiders total. The sheets of webbing in the ceiling covered an estimated 2 acres total, or about 8,000 square meters, while the cloud-like masses of webbing in other areas was about half that size and would have filled 23 railroad boxcars. The really interesting thing is that orbweaver spiders are usually solitary. Spiders may build webs near each other, but not usually like this. But these orbweavers lived in a place protected from wind and weather, and close to water, which attracted lots of midges and other small insects, and the presence of humans probably kept a lot of potential spider predators away, like birds. Life was good for these spiders and the scientists observed that they weren’t acting aggressively to each other, even when they were of different species. After studying the water treatment plant and its spiders, the team came to several conclusions. Since the spiders are harmless to humans, and are doing a really good job controlling the midge population, the scientists decided that pest control was not necessary and would even be a bad idea ...
