In many hymenocarines, including Balhuticaris , determining the exact number and types of appendages in their head remains difficult, which hinders a detailed understanding of the evolutionary relationships inside this group. Balhuticaris most probably belongs to the family Odaraiidae, a group of hymenocarines with highly multisegmented bodies, reduced or absent antennae and highly multisegmented legs.

Instead, these were identified as different undescribed euarthropods or potential radiodonts Nanglu et al.

In a surprising twist, a tweet on July 11, announcing an upcoming paper about a new Burgess Shale creature, received nearly 8, likes and over 2, retweets. The Burgess Shale is a huge deposit of fossils that dates back over million years to the Cambrian Period. Back then, a massive number of animals fell into something like a mudslide and were preserved almost in entirety. That means even their soft tissues, typically lost during the decomposition process when organisms are exposed to the weather, were left intact. The Cambrian Period that relates to the Burgess Shale is bookended by the Cambrian Explosion just before—an unfathomably large flowering of different species around the planet—and the mass extinction events that followed in intervals after, including the one that infamously killed off the dinosaurs. Between these mass extinctions, almost all the species on Earth were wiped out at different points, bottlenecking our evolution toward the present day. New species are being studied and taxonomized all the time, with well over species discovered to date. The peer-reviewed paper describing the newest one, Balhuticaris voltae , appears in the journal Cell.

Balhuticaris is a genus of extinct bivalved referring to the carapace hymenocarine arthropod that lived in the Cambrian aged Burgess Shale in what is now British Columbia around million years ago, balhuticaris voltae.

Balhuticaris is a genus of extinct bivalved referring to the carapace hymenocarine arthropod that lived in the Cambrian aged Burgess Shale in what is now British Columbia around million years ago. This extremely multisegmented with over segments arthropod is the largest member of the group, and it was even one of the largest animals of the Cambrian, with individuals reaching lengths of mm 9 in. Fossils of this animal suggests that gigantism occurred in more groups of Arthropoda than had been previously thought. The hymenocarines were an order of primitive mandibulates , the arthropod group that includes crustaceans , insects , myriapods and their relatives, that lived throughout the Cambrian period. This arthropod was described in based on 11 specimens found in the Burgess Shale between and , more specifically in the Marble canyon locality. By , scientists realized that these fossils represented a new species.

Eleven specimens of Balhuticaris voltae were collected from the Marble Canyon area of the famous Burgess Shale , a Cambrian-age fossil field in Canada. Yunnanocaris Xiazhuangocaris.

Covering the head of this creature was a large carapace that resembles an arch or other curved structure. The last segment is longer than the rest, and has a flattened triangular shape.

Balhuticaris voltae is the largest bivalved arthropod to date, at almost double the size of the previous record-holder, Nereocaris exilis. Life reconstruction of Balhuticaris voltae.

We have had many interesting discussions about how this animal lived, and some will remain unsolved until we discover further anatomical details. Each of these is subdivided into three segments, bears three spines on their outer edge and elongated filaments setae on their posterior edge. The exopod is ovoid, almost as long as the endopod. History of Research:. Occacaris Odaraia? Alejandro Izquierdo-Lopez: Balhuticaris was originally found in the latest Burgess Shale expeditions between and IScience, 25, Principal localities:. This is a group of jellyfish-like animals that exists today, but also had unique ecologies in the Cambrian. Caroline Delbert.
