Amazing fossil organs
The Chengjiang dodo deposit inChinahas yielded unbelievable fossils of arthropod Hammond organ system . These predatory animal lived 520 million years ago , during the Welsh period . Researchers have report the earliest examples of arthropod brainiac , heart stubble , heart and stemma vessels and digestive system from fossils discovered at Chengjiang . Here are some of these amazing fossil creatures .
Pumping blood
Fuxianhuia protensa , a 3 - column inch - long fogey found in sediments date stamp from 520 million years ago in China . This is an prototype of the creature ’s profligate vas system . The arthropod had a tubular heart locate near the back of its eubstance .
Hard shell
arthropod are known for their protective exoskeleton — modern examples include lobster and millipedes . This image shows the dorsal ( back ) view ofFuxianhuia protensa . part of the catgut are visible as dark stains along the animal ’s midplane .
Crustacean reconstruction
This figure of speech shows a schematic reconstruction of the peewee - like dodo , outlining the cardiovascular system in red , the encephalon and central nervous organization in gamey and the intestine in viridity .
Fossil head
The head region of Fuxianhuia from a fossil find reported in 2012 , show the nous and heart stalks .
Three-part brain
Iron - rich areas of the Fuxianhuia fogey , from 2012 , let on the imprint of an ancient mind .
Chengjiang arthropod
Fossil of the Alalcomenaeus , a megacheiran character of arthropod , a upstage congenator of scorpions and spider .
Early brain
This end - up of the promontory area of the Alalcomenaeus fossil specimen includes superimposed colours of a microscopy technique that reveal the distribution of chemic component in the fossil . fuzz shows up as blue , atomic number 26 as Battle of Magenta and the CT scan as unripened . The researchers used CT scans to make 3D reconstruction of features of the fossilized nervous arrangement . The scientists also used laser - scanning engineering to represent the distribution of chemical elements , such as iron and pig .
