List of index fossils. Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, Zone fossil is used when the fossil have all the characters ...Amazon.com: 524810 - Lophophyllidium proliferum - Lophophyllidium proliferum (Pennsylvanian) - Each : 工業與科學.The genotype of Lophophyllidium was designated as Lophophyllum proliferum (McChesney) by Grabau (1928, p. 99) in the original description of the genus, but some differences in interpretation of the type have developed.

The horn coral might be something in the family Hapsiphyllidae, perhaps Zaphrentites, or Lophophyllidiidae, like Lophophyllidium. They usually need to be sectioned for proper ID unless there are very few species known for that formation. I'd check the literature on the formation and see what's been recorded there.Specimens from Ohio are questionably referred to Lophophyllidium profundum (Edwards and Haime), a species that seems to be distinct from L. proliferum.

Right: solitary rugose coral Lophophyllidium proliferum from the Pennsylvanian Graham Formation of Coleman County, Texas (PRI 76802).

Image credit: Digital Atlas of Ancient Life, CC BY-NC-SA.Fang and Fan (1994) described and figured some corals from Xiaoxinzhai, such as Wannerophyllum exquisitum Fang and Fan, Lophophyllidium proliferum (McChesney), Lophophyllidium sp., and Thomasiphyllum sp. It seems difficult to evaluate the precise age by this coral fauna. However, Thomasiphyllum is generally indicative of pre-Capitanian Middle ...Expert Answer. The use of index fossils is advantageous when correlation stratigraphic sections over long distances. Index fossils have a short time span of occurrence and often fall within certain geologic time periods. Figure 7.2 shows a summary of relevant index fossils used in correlation efforts. During this lab exercise you will be using ... Question: The use of index fossils is advantageous when correlation stratigraphic sections over long distances.

Brachiopods are also common in this formation, but appear to be concentrated at several horizons.Lophophyllidium complexum, n. sp. Plate 3, figure 1. This species includes medium-sized solitary conical corallites having almost no curvature. The moderately thick theca shows wide rounded septal grooves and interseptal ridges. There are growth lines and low wrinkles transverse to these longitudinal markings. Question: The use of index fossils is advantageous when correlation stratigraphic sections over long distances. Index fossils have a short time span of occurrence and often fall within certain geologic time periods.Solitary rugosans (e.g., Caninia, Lophophyllidium, Neozaphrentis, Streptelasma) are often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall. Some solitary rugosans reached nearly a meter in length. However, some species of rugose corals could form large colonies (e.g., Lithostrotion ).

A young animal cemented itself to an object, growing wider as it grew skyward. Its weight eventually toppled the structure. Continued growth produced a bend, like a horn, and gave the coral its name. Syringopora grew as individuals not a true colony coral. They ...Lophophyllidium proliferum horn coral fossil found in the Kewitz Shale (Stanton Formation) of Cass County, Nebraska. Fossil dates to the Pennsylvanian period. Thanks to Mark for the fossil.
