Prehistorica (Christian M.) @prehistorica.art · 3h

Papiliomaris kluessendorfae, first reported in 1985 as the Waukesha "Butterfly Animal", was recently described as a strange bivalved arthropod with three pairs of large, feathery appendages. Some reports indicate it could reach up to 20cm wide.

New preprint led by grad student, Yu Mo! We introduce new software to calculate evolutionary rates of quantitative characters in the presence of discordance

Estimating the rate of quantitative trait evolution in the presence of gene tree discordance by calculating likelihoods across trees

Quantitative traits provide insights into how phenotypes evolve across species. However, standard comparative methods often assume a single species tree and overlook the discordant gene tree histories...

Our latest, led by Edu Ocaña-Pallarès and @ssolo.bsky.social, a timescale for fungal phylogeny that wrangles calibration from the unstructured fossil record of fungi and a history of horizontal gene transfers

www.nature.com/articles/s41...

A timetree of Fungi dated with fossils and horizontal gene transfers - Nature Ecology & Evolution

Combining fossil-based and molecular calibrations with data on horizontal gene transfer events, the authors develop a time-calibrated phylogeny of Fungi. This timescale, which integrates analytic uncertainties, suggests an older age of crown Fungi (1,401–896 million years ago), as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems (1,253–797 Ma).

化石・現生の無脊椎動物に関するサブカルや学術的な話題について語り合っているDiscordサーバーがあります（会話は英語です）．新たに出た論文もすぐに共有されたり（誰かが見つけたら）．注意：メンバーはほぼアマチュアで，かなりカジュアル／カオスな雰囲気なので，変なミームや投稿，型破りな仮説なども飛び交っています．参加希望の方はDMでご連絡ください．

There's a Discord server where people discuss fossil & extant invertebrates - from art and culture to academic topics. New papers sometimes get shared quickly (when someone notices).

Xiaolantianella longibicaudatus Guo et al., 2016 is a poorly known fossil ecdysozoan from the early Cambrian Chengjiang Biota, originally reported in a Chinese journal with poor discoverability. It is considered to belong to the extant priapulidan subfamily Priapulinae.

ともかく，この書籍を参考にする方は，記述を鵜呑みにせず，挙げられている引用文献に加えて他の文献も自ら調べ，よく確認することが不可欠かと思います．

『動物の系統分類進化学』（朝倉ら，2025），1時間程度で，特に系統や分類の部分をざっくり確認しました．全体的に，明らかな事実誤認，文献調査の不足，著しく（場合によっては20年以上）古い現在は変わっている見解，引用もなしに伝聞レベルの誤った記述をしている箇所などが多く見られ，特に各動物門を特定の人1人が担当した第II部で顕著です．問題箇所が多く，正誤表で対応できないと考えられるものも多いので，今後私の方でどうするか（e.g., 著者や出版社への連絡，問題点を指摘した論文の執筆）についてはとりあえず保留にしておきます．
