Lost Age of Monotremes Revealed by Fossils From 100 Million Years Ago

As bones encased in rock rotted away, water-borne silica seeped into the crevices, solidifying into opal and preserving precious details for 100 million years. The resulting fossils now provide evidence that there really may have been an Age of Monotremes, before other mammals came to dominate. "It's like discovering a whole new civilization," says Australian Museum paleontologist Tim Flannery. "Today, Australia is known as a land of marsupials, but discovering these new fossils is the first indication that Australia was previously home to a diversity of monotremes." Only five of these rare mammals still cling to existence: one platypus and four echidna species, shared between Australia and Papua New Guinea. But due to their reptilian-like egg-laying feature, it has long been thought these animals evolved before placental mammals like us and marsupials.

🪼Daily Cnidarian Fact:🪼

Upside-Down Jellyfish: Down is up for this jelly — it rests its bell on the seafloor and waves its lacy underparts up toward the sun. Why? This jelly is a farmer. Its brownish color is caused by symbiotic dinoflagellates living inside the jelly’s tissues. By lying upside-down, the jelly exposes its algae to the sun, allowing it to photosynthesize. The jelly can sustain itself off just the byproducts of the algae, and capture zooplankton for additional energy to grow.

do eastern hognoses get attacked by toads a lot? them being immune to their poison seems really specific

Quite the opposite! Many toads secrete toxins to avoid being eaten (most animals don't like eating poisonous food).

However, because they really like eating toads, hognose snakes have evolved specifically to be immune to those toxins. There are many examples of this kind of co-evolution in the animal kingdom (another common one are garter snakes and salamanders).

Fast Fauna Facts #3 - Winged Argonaut (Argonauta hians)

Family: Argonaut Family (Argonautidae)

IUCN Conservation Status: Least Concern

Like the other small octopuses in the argonaut family many Winged Argonauts appear to have spiral-shaped external shells similar to those of nautiluses or ammonites, but this isn't quite the case - what appears to be an argonaut's shell is only seen in adult females, and is actually a thin-walled, calcium-based case secreted from and held by a specialised pair of arms in order to carry fertilized eggs until they hatch. Found in non-polar waters worldwide, Winged Argonauts are found mainly near the surface in the open ocean (in contrast to most octopuses, which are bottom-dwellers,) feeding on small floating invertebrates and often using their suction cups to cling to flotsam or larger animals (sometimes including other argonauts) for protection; when faced with a predator, they may attempt to position the animal they're riding on between them and the perceived threat to act as a meat shield.

Fossil diatoms retain their intricately patterned glassy silica shell cases. Called frustules, these may be either rounded or elongated. Living diatoms are single-celled, algae-like protists. They make up much of the plankton in the marine and freshwater food chains. Their shells accumulate by the millions on the seafloor, eventually fossilizing to form a siliceous sedimentary rock called diatomite.

I thought this feisty little critter was an isopod until I got a closer look. This is a carrion beetle larva, and, as their name suggests, adults and larvae of this insect eat dead animals, maggots that live in carrion, and/or other types of decaying organic matter. I have no idea where this one came from, since there were no dead animals nearby or compost. Perhaps an insectivorous bird dropped it, or maybe this particular species likes chicken manure (there was a chicken tractor nearby vroom vroom). Putting this next part below the cut because it's a little gross. Proceed with caution:

This carrion beetle child seemed somewhat hungry, as it was nibbling at some dead skin around my finger nail. It tickled a bit and reminded me of the shrimp they sometimes have at aquariums that will nibble at your fingers. Yes that's a thing.

Orchid plants nurture their seedlings via shared underground fungal network, study shows

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by the wind, yet they often appear in clumps with small seedlings growing near mature plants. This phenomenon has puzzled ecologists since Darwin's time, with the exact reason remaining a mystery. A new study, led by researchers from the University of Sheffield in collaboration with The University of Manchester, provides the first evidence that early stage orchid seedlings germinate and thrive near to adult plants due to a kind of parental nurture using underground fungal networks. Scientists investigated the idea that fungal networks, known as mycorrhizal networks, act as a direct pathway for established orchid plants to share recently produced sugars with developing seedlings.
