Paraves is the taxonomic group that includes Dromaeosauridae, Troodontidae and Avialae, thus records origin of birds, evolution pennaceous feathers, their exaptation for flight.Non-destructive micro-X-ray fluorescence (micro-XRF) imaging technology was utilized to analyze two paravian fossil specimens, one referrable Microraptorinae (Dromaeosauridae) other Yanornithidae (Avialae).Both fossils are from Lower Cretaceous Aptian Jiufotang Formation, a Lagerstätte youngest stage famous Jehol Biota in western Liaoning, China.The analyses show bones preserve high amounts Calcium (Ca), Phosphorus (P), Sulfur (S), with significant heavy elements such as Strontium (Sr) Yttrium (Y) which may be related biological apatite.The preserved feathers Cuprum (Cu), Nickel (Ni) Titanium (Ti).The claw sheaths exhibit levels P Ca, suggests they were through phosphatization.Notably, large Ferrum (Fe) occur at intraskeletal joints both specimens trunk microraptorine.Further indicate enrichment Fe presence pyrite.The distribution indicates precipitation this element postburial taphonomic process.This micro-XRF data reveals different tissue types these provides information reconstructing processes responsible exceptional preservation Formation.
