They further show signs of pathological resin flow (Fig. 1e–g) induced by traumatic resinosis, a process that mobilizes resin to seal bark injuries typically resulting from parasites or forest fires (e.g. Langenheim Reference Langenheim2003, Brown et al.

Evidence for wildfires in late Cretaceous forests has been frequently reported from elsewhere but, so far, only rarely from polar biomes (Brown et al.

Reference Klages, Salzmann, Bickert, Hillenbrand, Gohl and Kuhn2020) explains the good preservation of the discovered amber with only rare peripheral signs of corrosion (i.e. high water levels quickly covered the resin and protected it from atmospheric agents such as ultraviolet radiation and oxidation; Langenheim Reference Langenheim2003). The newly discovered Antarctic amber further reveals potential tree bark remains preserved as micro-inclusions (Fig. 1e), hence indicating subaerial resin exudation on the plant's surface. The amber and its high amber-standard quality (i.e. solid, clear and translucent particles) indicate shallow burial, as amber would dissipate under increasing thermal stress with burial depth." Забавно, уже наблюдаю, что журналисты не сумели даже такой текст изложить корректно
Антарктида в мелу примерно там же находилась. Просто не было циркумполярного течения, которое отгораживало её от тёплых вод. И не было, соответственно, никакого ледяного щита. Климат был примерно похож на новозеландский. Может, немного прохладнее.

Какие журналисты - там ссылка на дзен. Весьма может быть, что они эту статью гуглом переводили
Значит там была какая то растительность, что очевидно, учитывая движение литосферных плит.
Всегда ваш, Капитан Очевидность

Вот это да, ученые в Антарктиде себе мозги ебут а тут на дтф все просто и понятно
Не трогайте, это на Новый Год
Лавкрафт давно все описал...
