Researchers have discovered two fossils that are 430 million years old which, they claim, contradict earlier beliefs about the origins of molluscs.
The specimens, known as Punk and Emo, were located in Hertfordshire and date back to an epoch when the majority of southern Britain was submerged under water, as stated by the University of Leicester.
Scholars indicated that this discovery has challenged the perception that early molluscs from a category called Aculifera were merely basic and primitive organisms.
The find has been represented through 3D modeling to provide a depiction of how the creatures looked.
Dr David Siveter, a palaeontologist at the University of Leicester, was part of a global team that unearthed the fossils.
Investigations revealed that Punk and Emo possessed smooth undersides, suggesting they likely resided on the ocean floor.
The results have been published in the journal Nature.
Dr Siveter remarked: “These fossils from 430 million years ago illustrate the critical significance of so-called ‘exceptional preservation,’ wherein the soft parts of the creature are fossilized, for understanding the evolution of life. In this case, it offers fresh insights on the early history of one of the fundamental branches of the evolutionary tree of a major life group on Earth, the molluscs.”
Today’s mollusc family encompassed snails, cephalopods, and mussels.
‘Exceptionally well preserved’
Leading the research was Dr Mark Sutton, affiliated with Imperial College London.
He stated: “The names Punk and Emo were initially conceived as our affectionate nicknames for these ancient molluscs, motivated by some of their distinct features and individuality.
“Punk, especially with its spiky appearance, strikingly resembles a defiant punk rocker, and we thought Emo was a fitting counterpart.”
He further noted: “Early Aculiferan molluscs are significantly less familiar than some of their relatives.
“There is scant information regarding this group, and for an extended period, we presumed they were rather elementary, uncomplicated, and primitive.
“Recovering fossils that are so exceptionally preserved and reveal details of the soft tissues is an extraordinary occurrence.
“We have succeeded in creating virtual fossils – 3D digital models – which provide us with a wealth of information, aiding our understanding that the evolution branch of molluscs containing Emo and Punk is much richer and more varied than we previously believed.”
