👉 The brachycentridae are a group of extinct, fossilized insects that lived in the Late Cretaceous period (approximately 68 to 57 million years ago). These creatures were characterized by their elongated body structures and specialized digestive systems. They had a long neck and a narrow mouth, which allowed them to consume small prey such as insects. The brachycentridae were found in various parts of the world, including Asia, Africa, and North America.
