Helix is a genus of large, air-breathing land snails native to the western Palaearctic and characterized by a globular shell. [1] [2] It is the type genus of the family Helicidae, and one of the animal genera described by Carl Linnaeus [3] at the dawn of the zoological nomenclature. Members of the genus first appeared in the fossil record ...
Stegoceras is a genus of pachycephalosaurid (dome-headed) dinosaur that lived in what is now North America during the Late Cretaceous period, about 77.5 to 74 million years ago (mya). The first specimens from Alberta , Canada, were described in 1902, and the type species Stegoceras validum was based on these remains.
Somatohelix is a genus of curvilinear, spiralling tubular fossil, 2–7 mm wide and 3–14 cm long, from the Ediacaran deposites of the South Australia that was originally interpreted as a trace fossil; a larger amount of better-preserved material since facilitated its reconstruction as the remains of an organism of uncertain nature.

Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
Fossils from the Ordovician are commonplace in the geologic formations which make up the Cincinnati Arch and are commonly studied along man made roadcuts. The Nashville Dome of Tennessee and the Jessamine Dome or Lexington Dome [ 1 ] of central Kentucky make up the central portion of the arch.
A Helix Fossil emote with the shortcut "PraiseIt" was later made available as a Twitch chat emote in celebration of the original Pokémon Red run. [77] On March 1, 2024, the official Pokémon Instagram account posted a video of various Omastar and Omanyte to commemorate the 10th anniversary of the original run’s completion. [78]
The relatively dome shape of the holotype indicates the specimen was an adult or nearing its completion of its adult transition. Consolidation between flat headed and domed pachycephalosaurs have been greatly debated. Fossils records from more numerous North American specimen suggest a flat domed juvenile stages.
Alaskacephale is an extinct genus of pachycephalosaurid, a group of dome-headed, herbivorous ornithischian dinosaurs, that lived during the Maastrichtian stage of the Late Cretaceous period in what is now northern Alaska [1] The genus is one of the few known Arctic dinosaurs and was found in the Prince Creek Formation, which preserves a menagerie of fossils.
