“…Here, we have tested this premise in an ancient group, well represented in the fossil record, for a topology that had several challenging nodes to recover. We expected the inclusion/exclusion of the debated yTriassolestodes asiaticus (Tierney et al, 2020) to have the greatest effect on the node age estimates due to its placement on an ancient node, crown-Epiprocata, on the Odonata tree. However, we find that removal of this fossil neither changes the recovered ages nor does it affect the precision of ages (Figure S4 and Table S4).…”

“…Divergence times estimation analysis. A recent study (Tierney et al, 2020) suggests that yTriassolestodes asiaticus is perhaps not an appropriate fossil for dating the crown Odonata node (see section ''Updated Kohli et al selection''). Additionally, we also determined that perhaps yProterogomphus renateae is more appropriately placed at the stem Gomphidae node rather than Crown Gomphidae node based on our current taxon sampling (see section ''Updated Kohli et al selection'').…”

“…The species was selected by Kohli et al (2016) as crown-Odonata resting on published accounts in which the species is assigned to the Triassolestidae, but without firmly establishing the placement of the species as crown-Odonata. Conversely, Tierney et al, (2020) argued that the Triassolestidae represent a paraphyletic assemblage of stem-Odonata, in which Triassolestodes asiaticus lacks the posterior lobe typical of the Lobodonata, including crown-Odonata and their closer stem-relatives. The latter includes the Mesophlebiidae and a number of 'fossil anisozygopterans' which all possess an open discoidal cell, thus precluding their assignment to crown-Odonata.…”

“…The oldest putative crown odonate fossil species belongs to the 250-millionyear-old extinct family Triassolestidae (see references cited by Kohli et al (2016)). However, this placement is debated and it is alternatively considered a stem lineage close to the crown (Tierney et al, 2020). Whether fossils are treated as crown-or stem-members of a particular group can dramatically influence the age of a particular node (example: Ruane et al, 2011), but the extent of this impact in other parts of the tree has not been well studied.…”

Dragonflies and damselflies are among the earliest flying insects with extant representatives. However, unraveling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic relationships, particularly in damselflies. Here we present a transcriptome-based phylogenetic reconstruction of Odonata, analyzing 2,980 protein-coding genes in 105 species representing nearly all the order's families. All damselfly and most dragonfly families are recovered as monophyletic. Our data suggest a sister relationship between dragonfly families of Gomphidae and Petaluridae. According to our divergence time estimates, both crown-Zygoptera and -Anisoptera arose during the late Triassic. Egg-laying with a reduced ovipositor apparently evolved in dragonflies during the late Jurassic/early Cretaceous. Lastly, we also test the impact of fossil choice and placement, particularly, of the extinct fossil species, yTriassolestodes asiaticus, and yProterogomphus renateae on divergence time estimates. We find placement of yProterogomphus renateae to be much more impactful than yTriassolestodes asiaticus.

On the contrary, we find that removal of this fossil neither changes the recovered ages, nor does it affect the precision of ages ( Supplementary Figures S4-1 Table S7).…”

SummaryDragonflies and damselflies, representing the insect order Odonata, are among the earliest flying insects with living (extant) representatives. However, unravelling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic relationships, an issue particularly prevalent in damselfly families and fossil lineages. Here we present the first transcriptome-based phylogenetic reconstruction of Odonata, analyzing 2,980 protein-coding genes in 105 species representing nearly all of the order’s families (except Austropetaliidae and Neopetaliidae). All damselfly families and most dragonfly families are recovered as monophyletic groups. Our Molecular clock estimates suggest that crown-Zygoptera (damselflies) and -Anisoptera (dragonflies) both arose during the late Triassic. Several of the observed long inner branches in our topology are indicative of the extinction of once flourishing lineages. We also find that exophytic egg laying behaviour with a reduced ovipositor evolved in certain dragonflies during the late Jurassic / early Cretaceous. Lastly, we find that certain fossils have an unexpected deterring impact in divergence dating analysis.
