“These fossils unmask the imposture”: amazing discovery in Greenland of a false octopus 500 million years old which upsets the history of the cephalopods

The recent fossil discoveries in Greenland have made it possible to lift the veil on a 300 million year old mystery. However, Nectocaridae, these enigmatic creatures similar to calmars, have long been a source of perplexity for scientists. Moreover, Thanks to in -depth research by the University of Bristol, the true nature of these creatures has finally been revealed. For example, Nectocaridae are not the ancestors of cephalopods. Similarly, as we thought before, but rather early descendants of arrow “these fossils unmask imposture”: amazing worms, which changes our understanding of marine evolution.

A fascinating paleontological discovery – "these fossils unmask imposture": amazing

The work of researchers from the University of Bristol have highlighted exceptionally well -preserved fossils discovered on the Sirius Passet site. Consequently, in the north of Greenland. Meanwhile, This site is renowned for its ability to preserve marine organizations from the Cambrian era with remarkable precision. In addition, Nectocarian fossils found on the spot allowed scientists to observe anatomical details hitherto unknown. Meanwhile, The discovery of delicately preserved nervous tissues has been decisive to resolve the enigma of their classification in the. For example, tree of life. For example, These fossils have revealed that the nectocidaries had mineralized nerve structures, characteristic of arrow worms, not cephalopods.

When was gas discovered for the first time?

The crucial role of the nervous system – "these fossils unmask imposture": amazing

Dr.. Jakob Vinther, from the University of Bristol, played a key role in this discovery. From the start, he suspected that the hypothesis of the cephalopods was wrong. The nectocarid fossils discovered at Sirius Passet confirmed his doubts by showing a preserved nervous system. including the ventral lymph node. The latter. a mass of nerves located on the belly of alive arrow worms was the key to correctly identify the nectocaridae. These unique anatomical characteristics have made it possible to establish resemblances to other chaetognath fossils. thus strengthening their classification as descendants of the arrow worms.

A complex. surprising anatomy

Nectocarid fossils have anatomical features as complex as they are fascinating. Unlike their modern descendants, these creatures had sophisticated “camera” eyes and long antennas, testifying to an impressive evolution. The ancestors of the arrow worms were therefore formidable predators. with advanced hunting capacities, long before the appearance of modern calmars. This discovery questions the supposed simplicity of the arrow worms. underlines their role as active predators in the ancient marine ecosystem.

A deserved tribute

The Nectocarida “these fossils unmask imposture”: amazing fossil was baptized Nektognathus Evasmithae in honor of Professor Eva Smith. a renowned human rights activist. Dr. Vinther judged this tribute appropriate, describing this creature as a “intelligent and stealthy fighter”. This discovery not only enriches our understanding of the evolution of marine species. but it also pays tribute to the contributions of those who worked to improve our understanding of the natural world.

This revelation on nectocaridae raises new questions about the evolution of marine species and their adaptation to their environment. How have these creatures evolved to become so effective predators in ancient seas. and what other mysteries remain to be discovered in the fossil archives?
