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 ...
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.

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 'tentacles' appear massed and stacked, with the fossil being tallest at the central dome and thinning out closer to its edges. [2] [1] Holdfast interpretation: There are two series of club-shaped 'lobes' radiating from the central dome of Eoporpita. The outer series of 'lobes' are all of relatively the same length, while the inner 'lobes ...
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.
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 dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective apices .
The iconic cranial dome found on Acrotholus makes it one of the earliest indisputable known members of the pachycephalosaur family. [1] Like others of its clade, Acrotholus was a bipedal herbivore characterized by a dome-shaped head. The dome had often been associated with intra-species combat though exact method of contact have been debated. [2]
