A 400-million-year-old “Excalibur worm” found | Digital Trends Spanish


A group of researchers discovered in Australia the remains of a prehistoric marine worm that inhabited more than 400 million years ago.

Its about Lepidocoleus caliburnus, whose main characteristic is to have had the body covered with plates of crystals. It is for this reason that it has received the name of Excalibur, which belonged to King Arthur, “guardian” of Great Britain in the 5th and 6th centuries according to English folklore.

Scientists claim that this specimen lived on coral reefs in shallow waters, which are now part of the Australian territory.

Those who found the remains argue that the worm used its plates to defend itself from predators and would have fed on organic waste.

The team behind this work has used a scanner in order to create 3D digital models on this type of shell.

“With the use of micro-CT, we can virtually separate the individual components of the armor,” explains researcher Sarah Jacket in a Science Alert article.

“We are able to manipulate the models to determine how individual pieces of the shell moved in relation to each other, as well as determine the degree of overlap between them.”

In this way, scientists have been able to detect a kind of armor that ran through the skeleton of this marine worm.

The authors of this work now want to investigate how this species used this sophisticated defense system against its enemies, for which they will once again create virtual models from the remains found.
