Umenocoleidae
Umenocoleidae is an extinct family of dictyopteran insects known from the Cretaceous. They are considered to be closely related to the Alienopteridae. They were originally considered to be beetles due to their beetle-like morphology, with sclerotised elytra-like forewings. This was probably an adaptation for living under bark and in other tight spaces.

Alienopteridae
Alienopteridae is an extinct family of dictyopterans, known from the Mid-Cretaceous to Eocene. They are noted for their unusual combination of features not found in other dictyopterans. Taxonomy It was originally assigned to its own order Alienoptera by Bai et al., 2016. It was reassigned to the dictyopteran superfamily Umenocoleoidea as sister family to the beetle-like Umenocoleidae by Vršanský ''et al.'' (2018), and a more recent analysis similarly places Alienopteridae and Umenocoleidae as sister taxa within Dictyoptera, but placing both lineages outside of Blattodea. A 2021 study revived the order Alienoptera for the clade containing Alienopteridae and Umenocoleidae, with a cladistic analysis placing Alienoptera as the sister clade to Mantodea (praying mantises). Distribution The majority of the alienopterid genera are known from the mid Cretaceous (latest Albian-earliest Cenomanian ~ 100 million years ago) Burmese amber found in Myanmar; though an additional two genera ...

Dictyoptera
Dictyoptera (from Greek δίκτυον ''diktyon'' "net" and πτερόν ''pteron'' "wing") is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea (termites and cockroaches together) and the order Mantodea (mantises). While all modern Dictyoptera have short ovipositors, the oldest fossils of Dictyoptera have long ovipositors, much like members of the Orthoptera. Classification and phylogeny The use of the term Dictyoptera has changed over the years, and while largely out of use for much of the last century, it is becoming more widely used. It has usually been considered a superorder, with Isoptera, Blattodea and Mantodea being its three orders. In some classifications, however, Dictyoptera is shifted to order status and in others the order Isoptera has been subsumed under Blattodea while retaining Dictyoptera as a superorder. Regardless, in all classifications the constituent groups are the same, just treated at different rank. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...
