The transition of the Jurassic to Cretaceous sequence in western Liaoning, northeastern china has become the focus for geologists and palaeontologists, especially due to the well-preserved Jehol Biota. In western Liaoning, the occurrence of early angiosperms and the "missing link" of fossil ginkgos in the Late Jurassic to Early Cretaceous provides great potential for exploring the macroevolution of plants. However, our knowledge for the biodiversity of late Mesozoic conifer plants in this region seems to be limited.

The early evolution of angiosperms has been a focus of intensive research for more than a century. The Yixian Formation in western Liaoning yields one of the earliest angiosperm macrofioras. Despite multitudes of angiosperm fossils uncovered, including Archaefructus and Sinocarpus, no bona fide normal flower has been dated to 125 Ma （mega-annum） or older. Here we report Callianthus dilae gen. et sp. nov. from the Yixian Formation （Early Cretaceous） in western Liaoning, china as the earliest normal flower known to date. The flower demonstrates a typical floral organization, including tepals, androecium, and gynoecium. The tepals are spatulate with parallel veins. The stamens have a slender filament, a globular anther, bristles at the anther apex, and in situ round-triangular pollen grains. The gynoecium is composed of two stylate carpels enclosed in a fleshy envelope, and develops into a ＂hip＂ when mature. Since the well-accepted history of angiosperms is not much longer than 125 Ma, Callianthus together with Chaoyangia, Archaefructus and Sinocarpus from the Yixian Formation demonstrate a surprisingly high diversity of angiosperms, implying a history of angiosperms much longer than currently accepted.

Searching for early angiosperms is a riveting activity in botany because it helps to resolve the phyiogenetic relationships among seed plants and among angiosperms themselves. One of the challenges for this job is what the target fossils look like. Most possibly early angiosperms may elude our scrutiny with gymnospermous appearances. This possibility becomes a reality in a Jurassic plant, Solaranthus gen. nov, which bears a peltaspermalean appearance and enclosed ovules. According to knowledge available hitherto, the latter feature makes it an angiosperm. However, such a feature is more likely to be eclipsed by its gymnospermous appearance. The early age and unexpected character assemblage of Solaranthus urge for a fresh look on the assumed-simple relationship between angiosperms and gymnosperms. Its resemblance to the order Peltaspermales favors the Mostly Male Theory.

A recently discovered megafossil of whole plant cycad is briefly reported here. The specimen is collected from the Yangcaogou Formation (Upper Triassic) in Changheying, Beipiao, Liaoning. The whole plant is preserved intact on a sandstone slab, 89 cm long and 130 cm wide, including leaves up to 82 cm long and a male cone physically attached to the stem apex. Analysis on the morphology, arrangement and venation of leaf and pinna, male cone and its relationship with other parts indicates that the fossil is closely related to living Zamiaceae in Cycadales. This cycad fossil is hitherto most completely preserved cycad specimen including both vegetative and reproductive organs. Its discovery contributes much to our understanding of the morphology and evolution of cycads, palaeoclimate as well as palaeoenvironment.

The Cycadales are one of the most ancient lineages of seed plants, with a fossil record that extends over 250 million years. Cycads are believed to have originated from the Late Palaeozoic, and reached its maximum diversity and distribution during the Mesozoic; however, their evolutionary history has remained relatively poorly understood. This largely results from the lack of anatomically well preserved fossil evidence and reproductive remains. In recent years, more researchers have carried out phylogenetic analysis using molecular approaches, and obtained exciting results, which broaden our knowledge of plant evolution. Meanwhile, more and more researchers have recognized that the fossil record is crucial for phylogenetic reconstruction of plant groups that have extensive evolutionary histories. Therefore, any discoveries of anatomically informative fossil with relation to cycadales or cycad-like plant taxa are of great importance to understanding of their evolutionary history.

新疆北部准噶尔盆地周边石炭系广泛出露,其中上石炭统发育海相火山—沉积序列,包括西准噶尔地区的哈拉阿拉特组、阿腊德依克赛组,东准噶尔地区的石钱滩组以及盆地南部的祁家沟组、奥尔吐组等。本文研究在上述各地层的灰岩层或夹层、碎屑岩中获得的四射珊瑚9属17种和床板珊瑚2属3种,对石钱滩组中的3个新种进行了详细的系统古生物学描述。上述珊瑚化石的地质时代主要为巴什基尔期至莫斯科期。在珊瑚动物群的组成上,哈拉阿拉特组中新发现Caninophyllum属分子,结合盆地东、西部共同产出的床板珊瑚Cystodendropora属分子,说明整个准噶尔盆地周边的动物群面貌大致类似,而西准噶尔地区的化石丰度、分异度显著低于盆地东部和东南部。综合前人资料,目前在准噶尔盆地周边发现的珊瑚化石有约一半为地方性分子。本文认为研究区珊瑚化石的分布和组成特征与晚石炭世准噶尔洋走向封闭或半封闭的演化趋势密切相关。

在对中国东北辽宁本溪中三叠统林家组的化石研究中,发现了木贼目瓣轮叶属一个新种——林家瓣轮叶(Lobatannularia linjiaensis ***.)。该种叶轮小,明显分成两瓣,每瓣叶数约10–12枚。叶线形至倒披针形,叶长差别大,叶联合长度占叶长约1/3–3/4。自1927年Kawasaki建立瓣轮叶属以来,该属已至少发现了33种,其中大部分报道于二叠纪,少数见于三叠纪。瓣轮叶属作为晚古生代华夏植物群孑遗分子之一,当前该属新种的发现不仅丰富了瓣轮叶属的分类多样性,而且拓展了对二叠纪-三叠纪之交生物大灭绝及之后复苏过程中瓣轮叶属演化趋势的认识。

地史中海相碳酸盐岩记录的无机碳同位素的波动经常与全球气候事件相互关联,但碳酸盐岩的碳同位素不仅与全球碳循环相关,也受控于区域水循环和成岩作用。晚古生代大冰期在石炭纪末—早二叠世达到最高峰,南方冈瓦纳大陆高纬度地区冰川的进退引起低纬度地区旋回性的海平面变化,并发育显著的沉积间断,在华南表现为喀斯特岩溶角砾岩等。本文选取安徽巢湖凤凰山剖面,对宾夕法尼亚亚系—乌拉尔统18m厚的碳酸盐岩地层(黄龙组和船山组)进行了详细的沉积学与碳同位素对比研究,以探索碳同位素变化的控制因素。本文共识别出厚层灰泥灰岩、厚层粒泥灰岩、中至厚层泥粒灰岩、厚层泥球颗粒灰岩、薄层鲕粒颗粒灰岩、厚至巨厚层生物碎屑颗粒灰岩、厚层核形石颗粒灰岩、薄至中层灰砾岩和炉渣状灰岩等9种沉积岩相,指示了多次暴露的碳酸盐台地环境。这些暴露特征与同时期贵州罗甸斜坡相碳酸盐岩序列(约194 m)对比,表明凤凰山剖面存在严重的地层缺失。揭示了研究层段11 m和14 m附近的碳同位素两次显著负漂(幅度约为6‰和7‰)与古喀斯特层对应,是由碳酸盐台地暴露引起的区域成岩改造导致的,而非源于引起气候变化的全球碳循环波动。因此,地层学、沉积学和地球化学等多学科综合交叉研究是深入揭示古气候和古海洋变化规律的重要前提。
