Unequivocal palaeontological evidence for viruses is usually absent. A specimen of the extinct predatory cockroach Stavba babkaeva gen. et sp. n. from Cretaceous Myanmar amber (98 Ma) shows symptoms of Deformed Wing Virus infection caused by pathogenic DWV-Iflavirus. The hindwing is undeveloped and both curled forewings are symmetrically deformed, differing from environmentally caused asymmetries known from Pripyat and Fukushima. While some unknown cockroach mutation might have the same symptoms, ontogenetic defects (such as incomplete moulting) differ in complete lack of sclerotization, modified forewing bases and presence onboth wings. Post-depositional, taphonomic influence can be excluded due to local character of the deformation (forewings on both sides) while other areas are undeformed. Drying shrinking can be excluded due to brittle character of the wing, which would crack instead – and it could not, be local either. Pathogenic RNA-viruses probably circulated among vertebrates and invertebrate decomposers/ predators in the dinosaur-age ecosystems. Our discovery complements an indirect putative evidence of Retrovirus infection that modified dinosaur bones.
对于病毒，通常没有明确的古生物学证据。已灭绝的白垩纪缅甸琥珀(98 Ma)捕食性蟑螂Stavba babkaeva gen. et sp. n.标本显示由致病性dwv - iflavvirus引起的变形翅病毒感染症状。后翼不发达，两个卷曲的前翼都对称变形，与普里皮亚季和福岛已知的环境造成的不对称不同。虽然一些未知的蟑螂突变可能有相同的症状，但个体发生缺陷(如不完全蜕皮)的不同之处是完全缺乏硬化，前翼基改变，并且在两只翅膀上都存在。沉积后，由于变形的局部特征(两侧前翼)，可以排除地学的影响，而其他地区则没有变形。由于机翼的脆性，可以排除干燥收缩，否则机翼会开裂，而且也不可能是局部的。在恐龙时代的生态系统中，致病性rna病毒可能在脊椎动物和无脊椎动物的分解者/捕食者之间传播。我们的发现补充了逆转录病毒感染改变恐龙骨骼的间接推定证据。
