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, balhuticaris voltae. 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 balhuticaris voltae Arthropoda than had been previously thought. The hymenocarines were an order of primitive mandibulatesthe arthropod group that includes crustaceansinsectsmyriapods and their relatives, that lived throughout the Cambrian period, balhuticaris voltae.

DOI: The origin of mandibulate arthropods can be traced back to the Cambrian period to several carapace-bearing arthropod groups, but their morphological diversity is still not well characterized. This species has an extremely elongated and multisegmented body bearing ca. Its unusual carapace resembles an arch; it covers only the frontalmost section of the body but extends ventrally beyond the legs. Balhuticaris had a complex sensory system and was probably an active swimmer thanks to its powerful paddle-shaped exopods and a long and flexible body.

Alternate artistic reconstruction of Balhuticaris voltae swimming upside-down. Hymenocarines were early arthropods with bivalved carapaces and mandibles, forming the bulk of the first mandibulates represented today by myriapods, crustaceans and insects Aria and Caron ; Vannier et al. 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. Balhuticaris has been found from both the Marble Canyon and the Tokumm Creek localities of the Burgess Shale during several expeditions between to The different specimens of Balhuticaris were originally not recognized as belonging to the same organism. Instead, these were identified as different undescribed euarthropods or potential radiodonts Nanglu et al. Balhuticaris is a large bivalved arthropod that can reach up to 25 cm in length. The carapace only covers the first quarter of the total body length. It has a dome-like shape. In frontal view, the carapace looks like an arch: each valve extends towards the ventral side of the animal, surpassing the length of the legs.

This balhuticaris voltae a group of jellyfish-like animals that exists today, but also had unique ecologies in the Cambrian.

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. Image credit: Hugo Salais. Balhuticaris voltae swam in the oceans of the Cambrian period approximately million years ago. At Balhuticaris voltae was likely a type of hymenocarine, a group of Cambrian arthropods that possessed bivalved carapaces and looked superficially like shrimps.

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.
