Cette formation riche en insectes [[fossiles]] a livré une variété de spécimens d'arthropodes fossiles, dont plusieurs ailes d'[[Odonates]] liées au genre ''Alloaeschna'' Wighton et Wilson, 1986. Nous démontrons ici que les caractères morphologiques précédemment utilisés pour séparer trois espèces sont plutôt le résultat de phénomènes intraspécifiques. Nous renforçons cette démonstration en utilisant deux exemples de forte variabilité et plasticité chez les espèces modernes de la famille des ''[[Aeshnidae]]''. En conséquence, nous avons réinterprété la position taxonomique d{{'}}''Alloaeschna marklae'' Wighton & Wilson, 1986 syn. nov. et ''Alloaeschna quadrata'' Wighton & Wilson, 1986 syn. nov. comme synonymes juniors d{{'}}''Alloaeschna paskapooensis'' Wighton & Wilson, 1986. De plus, nous décrivons la première occurrence d'un [[zygoptère]] dans la Formation de Paskapoo, à savoir ''Albertalestes paskapooensis'' gen. et sp. nov. (''[[Synlestidae]]''). Il est important de noter que ce nouveau taxon est le premier représentant de la famille trouvé en Amérique du Nord. Nous avons également reconstruit les relations au sein des ''[[Synlestidae]]'' sous inférences bayésiennes avec une matrice nouvellement assemblée. Enfin, nous discutons de la biogéographie du clade en considérant ses archives fossiles en utilisant la reconstruction parcimonieuse de l'état ancestral.</ins></div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>----</div></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>----</div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>'''Abstract''' - The Paleocene Paskapoo Formation in Alberta, Canada, offers a unique opportunity to gain insight into insect diversity at that time.

Here, we demonstrate that morphological characters previously used to separate three species are instead the result of intraspecific variability.
