Getting a Head on an Arthropod Fossil
There sure is a huge number of high-quality fossils coming out of China. While healthy skepticism is in order because of the people selling fakes in certain areas, the quantity is impressive. It may be that some are so plentiful, they are boring to scientists. Oh goodie, another trilobite...
Alert eyes can spot and reference something new or a superior specimen to something already known. Then they can use some of that impressive technology and get the details. This happened with a Kylinxia fossil and a CT scan.

Scientists have discovered that virtually all fossils found in the Cambrian sediments of the geologic column appear suddenly and are exceptionally preserved. One popular example is the complex, extinct invertebrate called the trilobite, with its thousands of named species.. . .Recently, paleontologists from Chengjiang Fossil Museum in China, and the Natural History Museum in London have redescribed an amazing fossil arthropod. It was unearthed in Cambrian (early Flood) sedimentary rock allegedly 520 million years old.. . ."The preservation of the fossil animal is amazing,” said lead author of the study Robert O'Flynn. In addition, “over 250 species of exceptionally preserved fossil organisms have been described” from the Chengjiang biota.
