AT the seventh and last of the ordinary monthly meetings of the Montreal Natural History Society for the season 1870–71 a communication on a Mineral Silicate injecting Palæozoic Crinoids was made by ...

A video has caught an underwater animal, which looks like a flower, practically jogging along the ocean bottom. The stalked crinoid spends most of its time sitting and catching food with the ...

The proposition is presented that the large thecae of many Paleozoic crinoids housed gonads, unlike modern crinoids that have the gonads on the arms or pinnules. Early in their history, inadunate ...

Nature abounds with examples of evolutionary arms races. Certain marine snails, for example, evolved thick shells and spines to avoid be eaten, but crabs and fish foiled the snails by developing shell ...

Japanese researchers recently set a record with the deepest in-situ observation of a criniod. In the words of the authors, Previous records of stalked crinoids from hadal depths (exceeding 6000 m) are ...

Finding parasites on fossils is a rarity, since, as we humans have experienced with a shudder, they tend to attach to skin or soft tissue and not skeleton. However, a discovery led by the University ...

ANN ARBOR, Mich.---With their long stalks and feathery arms, marine animals known as sea lilies look a lot like their garden-variety namesakes. Perhaps because of that resemblance, scientists had ...

The ocean floor is home to a menagerie of odd and peculiar creatures. Now, armed with a remote controlled vehicle, researchers in the South China Sea have discovered another. During surveys from the ...

Crinoids, a distant ancestor of today's sea lilies. Crinoids were abundant long ago, when they carpeted the sea floor. These echinoderms were at their height during the Paleozoic era. They could be ...

A new discovery suggests why one relationship evolved in appearance and how one parasite turned more aggressive but also protective toward its host over millions of years. Finding parasites on fossils ...
