Abstract
Tetrapods are rarely recovered from fossil resins, such as amber, and fossils of parasites are even rarer. We describe the first pre-Quaternary co-occurrence of ectoparasitic mites with hairs of their mammalian hosts, preserved in life-like detail from a piece of Eocene (∼ 40 Ma) Baltic amber. The mites, representing the oldest fossils of the family Myobiidae (Acari: Prostigmata: Eleutherengona), are described as Protohylomysobia erinaceophilus Sidorchuk & Bochkov gen. et sp. nov. and belong to the generic group Amorphacarus. Recent members of this group parasitize small-sized insectivores – shrews, moles and gymnures (Mammalia: Eulipotyphla: Soricidae, Talpidae and Erinaceidae: Galericinae). The fossils indicate that the evolution of Myobiidae and their relationships with mammals were well underway by the Eocene. The hairs of the hosts are also described, and are morphologically compared with those of Recent mammals. This comparison suggests an early-derivative member from an array of mammalian groups, a...

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...

Parasites are common in many ecosystems, yet because of their nature, they do not fossilise readily and are very rare in the geological record. This makes it challenging to study the evolutionary transition that led to the evolution of parasitism in different taxa. Most studies on the evolution of parasites are based on phylogenies of extant species that were constructed based on morphological and molecular data, but they give us an incomplete picture and offer little information on many importa...

Fossil ticks are extremely rare and Ixodes succineus Weidner, 1964 from Eocene (ca. 44–49 Ma) Baltic amber is one of the oldest examples of a living hard tick genus (Ixodida: Ixodidae). Previous work suggested it was most closely related to the modern and widespread European sheep tick Ixodes ricinus (Linneaus, 1758). Restudy using phase contrast synchrotron x-ray tomography yielded images of exceptional quality. These confirm the fossil’s referral to Ixodes Latreille, 1795, but the characters r...

Summary In the two decades since the discovery of feathered dinosaurs [1–3], the range of plumage known from non-avialan theropods has expanded significantly, confirming several features predicted by developmentally informed models of feather evolution [4–10]. However, three-dimensional feather morphology and evolutionary patterns remain difficult to interpret, due to compression in sedimentary rocks [9, 11]. Recent discoveries in Cretaceous amber from Canada, France, Japan, Lebanon, Myanmar, an...

Background The Mesopsychidae is an extinct family of Mecoptera, comprising eleven described genera from Upper Permian to Lower Cretaceous deposits. In 2009, several well-preserved mesopsychids with long proboscides were reported from the mid Mesozoic of Northeastern China, suggesting the presence of pollination mutualisms with gymnosperm plants and highlighting their elevated genus-level diversity. Since that time, additional mesopsychid taxa have been described. However, the phylogeny of genera...

Our knowledge of Cretaceous plumage is limited by the fossil record itself: compression fossils surrounding skeletons lack the finest morphological details and seldom preserve visible traces of colour, while discoveries in amber have been disassociated from their source animals. Here we report the osteology, plumage and pterylosis of two exceptionally preserved theropod wings from Burmese amber, with vestiges of soft tissues. The extremely small size and osteological development of the wings, co...

Architectonics of guard hairs from dogs of recent breeds, mongrel sled dogs, and fossil dogs from ancient settlements of Chukotka have been investigated using scanning electron microscopy. Distinct features of hair structure important for adaptation, including the adaptation to harness in sled dogs, were identified. Hairs of Chukchi sled dogs were most similar to those of the fossil dogs.

Modern tropical forests harbor an enormous diversity of squamates, but fossilization in such environments is uncommon and little is known about tropical lizard assemblages of the Mesozoic. We report the oldest lizard assemblage preserved in amber, providing insight into the poorly preserved but potentially diverse mid-Cretaceous paleotropics. Twelve specimens from the Albian-Cenomanian boundary of Myanmar (99 Ma) preserve fine details of soft tissue and osteology, and high-resolution x-ray compu...

Amber preserves microscopic, soft-bodies organisms and is a good medium in which to trace the evolution of pathogen–vector associations. Spirochetes-like cells (Spirochaetales: Spirochaetaceae) in the hemocoel and lumen of the alimentary tract of a larva tick (Amblyomma sp. Arachnida: Ixodidae) in Dominican amber are described in the collective fossil genus and species, Palaeoborrelia dominicanan. gen., n. sp. The size and shape of the fossil spirochetes closely resemble those of present-day Bor...

Animal colours can be richly informative about aspects of behaviour such as foraging ecology and mate preference. Birds in particular display many striking hues and complex patterns of pigmentation. Examples of plumage adaptations include brightly coloured feathers for enticing potential mates, as well as cryptic patterns that allow a bird to hide in plain sight1,2,3. By analogy with modern birds, the behaviours and habitats of ancient birds and other feathered dinosaurs may be inferred from pig...

ABSTRACTSmallness being in the essence of a mite, the question is whether it has always been so during the geological history of Acari. Here I assemble measurements of over 260 published mite fossils, distributed from the Early Devonian (410 mya) to the end of the Neogene (5 mya), and compare them to the data available for their extant relatives. A number of fossils are reconsidered: reports of the Ordovician Brachypylina and Permian Astigmata have to be excluded from the fossil record; Jurassic...

Abstract The oldest-known member of a small parasitic mite family Pterygosomatidae (Trombidiformes: Eleutherengona) was found in the Lower Cretaceous (Albian) amber locality of Archingeay-Les Nouillers in Charente-Maritime, France. The majority of the extant members of the family are obligate parasites of lizards, and only one genus of twelve, Pimeliaphilus Tragardh, 1905, is known to infest arthropods – kissing bugs, scorpions, beetles and cockroaches. The excellent preservation of the fossil, ...
