古生物学の研究チームは、約7000万年前のパタゴニア南部に生息していた新種のラプトル型恐竜を特定した。カンク・アウストラリス（Kank australis）と名付けられたこの恐竜は、現代のサギに近い適応能力を持ち、魚を捕食していた可能性が高い。
今回の発見は、アルゼンチンのサンタ・クルス州エル・カラファテ近郊にあるラ・アニータ農場で発見された歯、椎骨、足の骨などの化石に基づいている。ベルナルディーノ・リバダビア自然科学博物館のマティアス・モッタ博士率いる研究チームは、この種をウンエンラギア科の獣脚類に分類しており、成体の全長は2.5メートルから3メートルに達したと推定している。

A crushed dinosaur fossil, long forgotten in a drawer, has been reconstructed by a Virginia Tech undergraduate, unveiling a new species of early carnivorous dinosaur. The specimen, named Ptychotherates bucculentus, belonged to the Herrerasauria group and lived near the end of the Triassic period. Its discovery suggests this ancient dinosaur lineage persisted until the end-Triassic extinction.
Researchers from Australia and New Zealand have discovered fossils from 16 species, including a new ancestor of the kākāpō parrot, in a cave near Waitomo on the North Island. The remains, dating back about one million years, reveal waves of extinction driven by volcanic eruptions and climate shifts long before human arrival. The find fills a major gap in the country's fossil record.

Researchers have named a newly identified juvenile dinosaur species Doolysaurus huhmini, discovered on Aphae Island in South Korea. The fossil, the first from the country to include skull parts, reveals a turkey-sized animal that likely had a fluffy appearance and an omnivorous diet. The findings, led by Jongyun Jung, were published on March 19 in the journal Fossil Record.
