1.Title of the Study: Description of a Well Preserved Fetus of theEuropean Eocene Equid Eurohippussmesselensis2.Author name, credentials:

Dr.Jens Lorenz Franzen, Germany professor in Paleontology

Dr.Jorg habersetzerProfessor in Paleontology

Dr.Christine Aurich Professor in Veterinary Medicine3. In yourown words, state the purpose of the study: Was to clearly showpresence of fetus and reproductive soft tissue in a fossil.4.Identify literature written about the problem: Fossil record ofmammals is restricted to isolated teeth and bones, less than 2% oflocalities with fossil have yielded nothing more than fragments ofjaws and other bones. Skeletons of pregnant female with fetus areextremely rare. The soft tissue is outstanding well preserved.Identification of individual bones primary attributed to micro-x-ray.Most of the bones are articulated at nearly original position.5.State the theory, concepts and the relationship to science: Thetheory behind preservation of soft tissue is based on presence ofbacteria metabolism on the soft tissue. The bacteria preservationenables scientist especially paleobiologist to relate the fossiluterus with modern horse enabling them to shade light on evolutionaryof mammals.6. State the research problem or hypothesis: is itpossible to preserve the soft tissues of a fossil in reproductivesystem?7. List the dependent and the independent variables .Thepreservation of the soft tissue dependent on bacterial metabolismwhile the identification of fetus is determine by the time of its agefrom conception to birth.8. State all definitions given:

Paleobiology-means, the study between relationship of biology and environment.

Uteroplacenta-termused to refer to uterus and placenta

Eurohippussmesselensis-means extinct genus of equid unglate9.List the tools with their reliability and validity information: highresolution micro-x-ray was key in identification of bone structures.Scanning electronic microscopy was used to identify the bacteria andprove the existence of soft tissues. The results from the above toolswere reliable and valid as they are not biased.10. Describe thesample: It was identified as Eurohippussmesselensiswith fetus and soft tissue of placenta.11.Describe the ethics of the study, that is the IRB (Look up): Thesample was identify through classic anatomy and osteologymethods.12. State the data collection process: Most of the datawas collected through observation of micro-x-ray photographs andscanning electronic microscopy.13. Discuss the data analysis:The data was analyzed in figure form. Comparison between the fetusbones and it mother were compared in a table.

14Discuss results, recommendations, and implications for futurepractice. The results from the data and research undertaken provedthe hypothesis o be true. The authors recommended that the study ofEurohippussmesselensisis crucial in shedding light in paleobiology and evolution ofmammals.
