What are the physical characteristics of Perisphinctes tiziani?
What are its physical characteristics? Biological Evolution and/or Phylogeny? The Perisphinctes Tiziani is a distant relative of molluscs, squid, and octopi. The Perisphinctes Tiziani fossil looks like the common shell of a snail, but with ribs going around the spiral of the shell.
Where can Perisphinctes be found?
Distribution. Shells of species belonging to this genus have been found in the Jurassic of Antarctica, Argentina, Chile, Cuba, Egypt, Ethiopia, France, Germany, Hungary, India, Iran, Italy, Japan, Madagascar, Poland, Portugal, Russia, Saudi Arabia, Spain, Switzerland, the United Kingdom and Yemen.
What environment did the Perisphinctes live in?
Habitat. It is thought that Perisphinctes lived in shallow water, in the inner part of the continental shelf and shelf seas interior, like all forms of the same family ( Perisphinctidae ). This ammonite was a form cosmopolitan, widespread in warm-temperate waters worldwide.
What features do ammonites have that make them excellent guide fossils for the Mesozoic?
Ammonites make excellent guide fossils for stratigraphy because:
- they evolved rapidly so that each ammonite species has a relatively short life span.
- they are found in many types of marine sedimentary rocks.
- they are relatively common and reasonably easy to identify.
- they have a worldwide geographical distribution.
Why are ammonites considered excellent index fossils?
Ammonoids are important index fossils because of their wide geographic distribution in shallow marine waters, rapid evolution, and easily recognizable features. These forms are characterized by an interwoven suture called the ammonite pattern.
What can we infer about ammonites from similarities to modern day organisms?
Scientists believed that ammonites, like modern cephalopods, had soft body tissue with tentacles attached to their heads for catching prey. Fossil evidence indicates they had sharp, beaklike jaws to snare prey such as plankton, crustaceans, and other ammonites. They were also preyed on by larger reptiles and fish.
Are there ammonites today?
The chief city of the country was Rabbah or Rabbath Ammon, site of the modern city of Amman, Jordan’s capital. Milcom and Molech are named in the Hebrew Bible as the gods of Ammon. The people of this kingdom are called “Children of Ammon” or “Ammonites”….Ammon.

What was the time period of the Perisphinctes?
Perisphinctes is an extinct genus of ammonite cephalopod. They lived during the Middle to Late Jurassic epochs and serve as an index fossil for that time period.
What do you mean by antecedent of behavior?
In technical terms, antecedents of behavior are stimulus events, situations, or circumstances that precede an operant response (Miltenberger, 2004). In Laymen terms, an antecedent is what was happening or what/who was present right before the behavior occurred.
How to create an antecedent behavior consequence chart?
You can create an Antecedent-Behavior-Consequence chart by drawing a table with four columns. Each time the behavior occurs, you’ll fill out a new row and date each entry. This will make it easier to compare each event. Here is a sample ABC Chart:
How to manipulate antecedents to increase desirable behavior?
Also by bringing a healthy lunch to school makes it more likely your child will eat the healthy food which takes less effort than getting up and standing in line for an unhealthy school lunch. Three ways to manipulate antecedents to increase a desirable behavior are: 1) Present the cues for the desired behavior in the child’s environment.
