В янтаре обнаружен клещ, пивший кровь динозавров

Длина клеща, застывшего в янтаре, составляет 0,5 сантиметра. Без малого 100 миллионов лет назад он обитал на территории современной Мьянмы. Изучить кровь, которую он выпил, пока невозможно, поэтому нельзя сказать наверняка, что она принадлежит именно динозаврам, однако специалисты полагают, что это так. Что касается пера, оно, по всей вероятности, принадлежало хищному динозавру из группы теропод, то есть сравнительно близкому родственнику современных птиц. Также специалисты обнаружили останки ещё двух насекомых, предположительно откладывавших яйца в гнёздах динозавров.

По мнению исследователей, находка может говорить о том, что птицы и клещи, пьющие их кров, могли совместно эволюционировать на протяжении сотни миллионов лет. Исследование было опубликовано в журнале Nature Communications.

Долгое время учёные не знали, что многие динозавры были покрыты перьями — в этом «подозревали» лишь непосредственных предков современных птиц. Тем не менее, с середины 90-х годов прошлого века у специалистов появляется всё больше доказательств, что оперение было весьма распространённым явлением среди древних ящеров. В частности, наличие перьевого покрова твёрдо установлено у представителей 8 семейств хищных динозавров, принадлежащих к подотряду теропод (к которому относятся, в том числе, и тираннозавры). К слову, недавно учёные предположили, что тираннозавры напоминали некоторых современных птиц и своим «голосом» — во всяком случае, так считает Джулия Кларк из Техасского университета в Остине. А недавно палеонтологи обнаружили древнего динозавра, не только оперением, но и в целом внешним видом весьма похожего на современных гусей.
