A new fossil shrimp species has been identified in China
The new species is named Innovatiocaris maotianshanensis, according to data from the Nanjing Institute of Geology and Paleontology (NIGPAS) of the Chinese Academy of Sciences. It was previously known as anomalocaris, meaning abnormal shrimp, because its appearance is very similar to the already known radiodonts.
Fossils of the new shrimp species were collected from the Early Cambrian fauna in the Chenjiang sedimentary bed in the Maotianshan Mountains. They are very similar to Radiodon, with a streamlined body with paired blades and gill valves for swimming and breathing, a pair of spiny claws, and a pair of large compound eyes on the head and radial mouthparts under the head.
However, Innovatiocaris maotianshanensis has a pair of particularly long tail forks, and the morphological details of its front paws differ markedly from those of Anomalocaris.
The researchers also conducted an evolutionary analysis of the genus, showing that Anomalocaris was very close to its evolutionary starting point. The new discovery also provides important clues for understanding the evolution and ecology of early arthropods during the Early Cambrian, according to the scientists.
