How the fossil record was recorded for a rare or abundant species during catastrophic event of mass extinction. Concept introduction: The large number of species is becoming extinct throughout all geographic locations of the earth and is called as mass extinction of species. This extinct species is documented in the fossil record. This mass extinction is mainly due to the destruction of species habitat and changes in environmental conditions, which is not favorable to the species. About 50% of marine species have become extinct, as well as plants and animals. Mass extinction changes the ecological communities and there is disappearance of evolutionary lineage between the species. It requires more than 5 million years to recover from a mass extinction. Thus, it promotes the adaptive radiation to recover from mass extinction.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
