Ticks are currently among the most prevalent blood-feeding ectoparasites, but their feeding habits and hosts in deep time have long remained speculative. Here, we report direct and indirect evidence in 99 million-year-old Cretaceous amber showing that hard ticks and ticks of the extinct new family Deinocrotonidae fed on blood from feathered dinosaurs, non-avialan or avialan excluding crown-group birds. A †Cornupalpatum burmanicum hard tick is entangled in a pennaceous feather. Two deinocrotonids described as †Deinocroton draculi gen. et sp. nov. have specialised setae from dermestid beetle larvae (hastisetae) attached to their bodies, likely indicating cohabitation in a feathered dinosaur nest. A third conspecific specimen is blood-engorged, its anatomical features suggesting that deinocrotonids fed rapidly to engorgement and had multiple gonotrophic cycles. These findings provide insight into early tick evolution and ecology, and shed light on poorly known arthropod–vertebrate interactions and potential disease transmission during the Mesozoic.

Although reconstruction of the phylogeny of living birds has progressed tremendously in the last decade, the evolutionary history of Neoaves—a clade that encompasses nearly all living bird species—remains the greatest unresolved challenge in dinosaur systematics. Here we investigate avian phylogeny with an unprecedented scale of data: >390,000 bases of genomic sequence data from each of 198 species of living birds, representing all major avian lineages, and two crocodilian outgroups. Sequence da...

Abstract. The results of a phylogenetic analysis of Dermestidae (Coleoptera) based on the morphology of immature stages are presented and implications for the classification of the family are discussed. The monophyly of ((Orphilus) + (Dermestidae) + (Endecatomidae (Bostrichidae + Anobiidae))) is strongly supported. Dermestidae, excluding Orphilus Erichson, forms a monophyletic group. The phylogenetic position of the Orphilinae remains enigmatic. The hypothesized relationships of the remaining de...

Abstract Nuclear ribosomal RNA (18S and 28S rRNA) and mitochondrial genomes are commonly used in tick systematics. The ability to retrieve these markers using next-generation sequencing was investigated using the tick Nuttalliella namaqua . Issues related to nuclear markers may be resolved using this approach, notably, the monotypic status of N. namaqua and its basal relationship to other tick families. Four different Illumina datasets (∼55 million, 100 bp reads each) were generated from a singl...

Abstract The structure of bird feathers is reviewed. Features of the feathers, including SEM examination of nodes, were selected giving discrimination at least at the order level. Quantitative data for these are presented.

Two mammalian hairs have been found in association with an empty puparium in a ∼100-million-year-old amber (Early Cretaceous) from France. Although hair is known to be an ancestral, ubiquitous feature in the crown Mammalia, the structure of Mesozoic hair has never been described. In contrast to fur and hair of some Jurassic and Cretaceous mammals preserved as carbonized filaments, the exceptional preservation of the fossils described here allows for the study of the cuticular structure.

Abstract Although dinosaur eggs were first discovered and identified in the late 1800s, limited attention was given to the scientific value of oological fossils in contrast to observations based on skeletal features. Here, we offer a review of Mesozoic saurischian egg materials, in comparison with extant crocodilians and avians, and their paleobiological interpretation based either on the presence of embryos in ovo or brooding adults on egg clutches. Our study focuses on the eggs of the ovirapto...

Abstract Three new genera and four new species representing Erythraeidae ( Burerythrites pankowskii gen. et sp. nov., Burphanolophus joergwunderlichi gen. et sp. nov.), Smarididae ( Burfessonia maryae gen. et sp. nov.) and Trombellidae ( Nothrotrombidium myanmarum sp. nov.) (Arachnida: Trombidiformes, Parasitengona) are described from the Upper Cretaceous (Albian) Burmese amber. Other erythraeoid and trombidioid mites, not identified to the species level, including larvae attached to nematoceran...

The first fossil potentially assignable to the extant hard tick genus Haemaphysalis CL Koch (1844) (Ixodida: Ixodidae) is described from the Late Cretaceous (ca. 99 Ma) Burmese amber of Myanmar. Haemaphysalis ( Alloceraea ) cretacea sp. nov. is the oldest and only fossil representative of this genus; living members of which predominantly feed on mammals. Their typical hosts are known since at least the Jurassic and the discovery of a mid-Cretaceous parasite, which might have fed on mammals raise...

Abstract A unique inclusion from Cretaceous (ca. 100 Ma) Burmese amber from Myanmar is described comprising a fossil hard tick (Parasitiformes: Ixodida: Ixodidae) wrapped in spider silk. Fossil ticks are very rare. Those from Burmese amber are the oldest examples of Ixodida recorded so far, and this is also the first time that this specific interaction between ticks and spiders has been documented in the fossil record. Spiders occasionally prey on ticks in modern ecosystems. However, those famil...

Although Ixodes scapularis and other related tick species are considered prolific vectors for a number of important human diseases, many aspects of their biology, microbial interactions and immunity are largely unknown; in particular, how these ancient vectors recognize invading pathogens like Borrelia burgdorferi and influence their persistence. The analysis of the Ixodes genome and a limited set of transcriptomic data have established that ticks encode many components of classical immune pathw...

The fossil record of ticks has been classically used to discern the probable vicariance events of these arthropods, and to date the split moments of the different lineages. Although new techniques based on molecular clock methods are already available, tick fossil record still stands as a valuable source of information if correctly interpreted. Here we report about a male specimen of Ornithodoros (Alectorobius) sp. found in Dominican amber of about 25 millions years, illustrating its main morpho...

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, ...

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 systematics of the genera and subgenera within the soft tick family Argasidae is not adequately resolved. Different classification schemes, reflecting diverse schools of scientific thought that elevated or downgraded groups to genera or subgenera, have been proposed. In the most recent classification scheme, Argas and Ornithodoros are paraphyletic and the placement of various subgenera remains uncertain because molecular data are lacking. Thus, reclassification of the Argasidae is r...

Since ancient times, philosophers and taxonomists have tried to classify forms of life. This is what taxonomy is about: the science of identifying, naming, classifying, and describing organisms. In this article I address the issue of the species concept in tick taxonomy. While the typological species concept is still the most widely used, the biological and phylogenetic species concepts are growing in popularity among tick taxonomists. The integrative approach is increasingly being used, but the...
