Sinraptor hepingensis, formerly referred to Yangchuanosaurus, is a second species referred to this genus. [1] However, the identity of this species within Sinraptor is questioned by other paleontologists, [7] [8] and the describers of Alpkarakush included this species within Yangchuanosaurus based on their phylogenetic analysis in 2024.

In 2023, several lancetfish have washed up on the coastline of beaches of Oregon. While the fish tend to live in tropical or subtropical water, they often need to travel to Alaska's Bering Sea to find food. Beach-goers that see the fish have been requested to take a photo and tag the NOAA Fisheries West Coast region. [13]
A paleontologist hailed the discovery as "truly an unusual find," adding it helped explain the relationships in the prehistoric food chain.
It had an enlarged nose similar to its contemporary Altirhinus, but it is most likely a separate taxon [31] Chuandongocoelurus: 1984 Shaximiao Formation (Middle Jurassic, Bathonian to Callovian) China: A tetanuran of uncertain relationships Chuanjiesaurus: 2000 Chuanjie Formation (Middle Jurassic, Bathonian) China
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. Researchers from the University of New Mexico Health ...
Needlefish (family Belonidae) or long toms [2] are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., Strongylura), while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon.
