Abstract
AbstractBurmese amber is an extremely important source of mid-Cretaceous plant and animal remains with over 870 species of organisms, ranging from protozoa to vertebrates, described from this source. The amber mines are located on the West Burma Block that according to geologists was originally part of Gondwana. The present study introduces some angiosperms and insects in Burmese amber whose closest extant relatives have a Gondwanan distribution and there is no previous evidence of a Laurasian distribution. Based on this evidence, it is proposed that organisms in Burmese amber represent a selection of tropical to subtropical life forms that inhabited the interconnected continents of Gondwana in the Early Cretaceous. Based on the fossil record of angiosperms and their diversity in Burmese amber, the West Burma Block could not have rafted from Gondwana to SE Asia before the Early Cretaceous.

Fossil jacobsoniids are rarely discovered. Here the earliest representative of the enigmatic polyphagan family Jacobsoniidae is described and figured. A new species belonging to the extant genus Sarothrias Grouvelle, †Sarothrias cretaceus sp. nov., is preserved in the Upper Cretaceous amber from Myanmar, representing the first fossil Jacobsoniidae from the Mesozoic. Sarothrias cretaceus is most similar to the Recent species S. audax Ślipinski & Lobl from the Tanimbar Islands of East Indonesia, d...

Abstract The fossil flower Tropidogyne pikei Chambers, Poinar & R. T. Buckley, previously described from Burmese amber has five spreading, epigynous sepals with five major veins and branched, anastomosing veinlets. On top of the inferior ovary is a broad, flat nectar gland from which project three short, arched styles (Chambers et al. 2010). The present paper describes the flowers of another species of this genus, T. pentaptera sp. nov., based on seven separate specimens from the same amber bed....

Amblyomma birmitum sp. nov. is formally described as a new record from 99 Ma old Burmese amber from Myanmar. This confirms the presence of the extant hard tick genus Amblyomma C.L. Koch, 1844 (Ixodida: Ixodidae) in the Late Cretaceous. This discovery is placed in its wider context and some reports of fossil hard ticks, such as a Hyalomma C.L. Koch, 1844 in Eocene Baltic amber, are misidentifications. The genus Amblyomma belongs to the clade Metastriata, a group which probably also accommodates t...

The Burma Platelet covers the western part of Myanmar, lying between the Indian Plate with the attached Bengal Basin in the west and the Sunda Plate in the east. This platelet is also jammed between the volcanic ridges on the Indian Plate in the south and the Shillong continental buttress in the north. The tectonic boundaries of the platelet are the active Sagaing dextral strike-slip fault in the east, and the debatable Bengal Basin subduction zone in the west. This non-rigid sliver plate has ac...

The floral history of early angiosperms is far from complete. The fossil discussed here has the potential to expand our knowledge of timing, reproductive biology, and paleobiogeography in early angiosperms.Cutting-edge methodologies in CT scanning in conjunction with tomography software have opened new possibilities for discovering details in amber-preserved fossils that were inaccessible for meaningful study in the past.The fossil is small and complex, cupulate, with numerous stamens and a suit...

This paper represents the first formal description of a Cretaceous terrestrial isopod (Oniscidea). This unique specimen, a well preserved female in Burmese amber from Myanmar, is described as Myanmariscus deboiseae gen. nov. sp. nov. It belongs to the clade Synocheta Legrand, 1946 based on the poorly differentiated flagellum of antenna, its small body size and underdeveloped eyes. Its familial position remains uncertain because this group is primarily classified using male reproductive structure...

A fossil opilioacarid mite (Parasitiformes: Opilioacarida) in Burmese amber is described as ?Opilioacarus groehni sp. nov. This ca. 99 Ma record (Upper Cretaceous: Cenomanian) represents only the third fossil example of this putatively basal mite lineage, the others originating from Eocene Baltic amber (ca. 44–49 Ma). Our new record is not only the oldest record of Opilioacarida, but it is also one of the oldest examples of the entire Parasitiformes clade. The presence of Opilioacarida—potential...

Abstract It is widely accepted that deformation of the India/Sunda plate is the result of partitioned hyper oblique convergence. Presently, sub-meridian dextral strike slip faulting accommodates this India/Sunda motion in a buffer zone, the Burma platelet. This wide dextral strike slip shear zone is complicated by the side effect of the Tibet plateau collapse that can be described in term of crustal flow and gravity tectonics. The loss of potential energy related to this plateau collapse affects...

†Mesopassandra keyao gen. et sp. nov., representing the first Mesozoic record of the family Passandridae (Coleoptera: Cucujoidea), is here described from Upper Cretaceous Burmese amber. Based on a phylogenetic analysis of 30 adult characters †Mesopassandra was recovered as the sister group to all remaining Passandridae, having a large labrum, bidentate mandibles and presumably 5-5-4 tarsi in the male. It is here placed in a new subfamily, †Mesopassandrinae subfam. nov. Ancestral area was reconst...

Abstract Kryzhanovskiana olegi gen. et sp. nov. is described from Cenomanian Burmese amber within the tribe Metriini (Paussinae). By having some peculiarities in the body shape and structure of the head (elongate mandibles, reduced eyes, additional setigerous pores on frons and vertex), the new genus is rather distinct from the two modern genera Metrius Eschscholtz, 1829 and Sinometrius Wrase et Schmidt, 2006, each with restricted distribution in western North America ( Metrius ) and in East Asi...

Convergence between the Indian and Asian plates has reshaped large parts of Asia, changing regional climate and biodiversity, yet geodynamic models fundamentally diverge on how convergence was accommodated since the India–Asia collision. Here we report palaeomagnetic data from the Burma Terrane, which is at the eastern edge of the collision zone and is famous for its Cretaceous amber biota, to better determine the evolution of the India–Asia collision. The Burma Terrane was part of a Trans-Tethy...

Fossil records of piestine rove beetles are very limited, with only two definite species from Mesozoic Chinese compressions, a single taxon from mid-Eocene Baltic amber and a doubtful Oligocene compression fossil from France. Here, a remarkable new genus and species, Propiestus archaicus gen. et sp. nov., is described based on a well-preserved individual in Upper Cretaceous Burmese amber from northern Myanmar (Cenomanian, c. 99 Ma). It represents the first piestine fossil found in Mesozoic amber...

Abstract Mid-Cretaceous amber from Myanmar, also known as “burmite”, has produced 1013 species of which 693 are Insects. The Mesozoic cockroach record is rich, with thousands of specimens that show diverse ecological adaptations. Cretaceous cockroaches in amber have been reported from Lebanon, Taimyr, New Jersey and France. Cockroaches from Myanmar amber are represented by at least 74 species, of which 14 are formally described. Spinaeblattina with S. myanmarensis gen. et sp. nov. and S. yixiane...

Morphological insect-insect mimicry is known from few Cretaceous cockroaches and a beetle. Formicamendax vrsanskyi gen. et sp. n. (Blattaria, Alienopteridae) shows myrmecomorph features such as an elongated, smooth and black body, simple fenestrated hindwing, legs lacking protective spines. Elbowed or “geniculate “antenna is a typical character of advanced ants and weevils used for different forms of communication. Together with reduced mouthparts and specialized palps still preserved grasping f...

Abstract Fossil records of the ancient and less studied millipede order Siphonophorida are rare and only known from Oligocene-Miocene Dominican amber to date. Here, we describe a Mesozoic species of this order, Siphonophora hui sp. nov., based on two well-preserved specimens from mid-Cretaceous Burmese amber. The new species can be placed in the family Siphonophoridae by having mouthparts strongly modified into a long beak, straight antennae, the separation of tergites, pleurites and sternites, ...
