封面说明：辽西早白垩世热河生物群朱氏莫干翼龙生态复原图。朱氏莫干翼龙(Moganopterus zhuiana)具有梳颌翼龙类中目前发现的最大头骨，包括头嵴在内，全长接近1 m。新研究认为这一种类具有100枚细长牙齿，营滤食生活。依据梳颌翼龙类翼展和头骨长度的线性关系，重新推测了莫干翼龙的翼展。新的推测结果证实，虽然比最初推测的小了很多，但莫干翼龙仍然是已知的个体最大的梳颌翼龙类。对比侏罗纪和白垩纪的梳颌翼龙类，这一类群的体型大致存在着增大的趋势。详见本期高殿松等人文。(绘图：王晨琪)
Cover image: The reconstruction of Moganopterus zhuiana from the Early Cretaceous Jehol Biota of western Liaoning. Moganopterus zhuiana has the largest skull in ctenochasmatids thus far, nearly one metre including the posterior crest. It has 100 slender teeth and is assigned to the filter ctenochasmatids in the new study. Its wingspan was re-estimated according to a simple regression equation for wingspan versus skull length in ctenochasmatids. It confirmed that M. zhuiana, although smaller than previous thought, was still the largest known ctenochasmatid. When comparing the sizes of ctenochasmatids in the Jurassic and Cretaceous, ctenochasmatids showed a rough tendency to increase their sizes. See details in the paper of Gao et al. (p.) (Illustrated by Wang Chenqi).
