Musang (Paradoxurus hermaphroditus) merupakan hewan carnivore yang tergolong family Viverridae dan termasuk dalam CITES (Convention on International Trade in Endangered Spesies) tingkat Appendix-III. Populasi hewan ini tersebar di Jawa, Sumatera, Kalimantan, Sabah, Serawak, Nusa Tenggara, Sulawesi, Asia Tenggara, Sri Langka dan India. Studi osteologi cranium tentang musang belum banyak dilakukan. Penelitian ini bertujuan untuk mengetahui struktur anatomi secara makroskopik cranium musang meliputi studi morfologi dan morfometri osteologi. Penelitian ini menggunakan cranium musang sebanyak 5 buah dengan ratarata berat badan dibawah 1 kg yang diperoleh dari daerah Muntilan dan Yogyakarta. Studi morfologi dilakukan dengan mencermati cranium musang dan membandingkan dengan anjing dan carnivore lain. Kajian morfometri dilakukan dengan mengukur panjang dan lebar serta menghitung index beberapa titik pengukuran. Morfometri cranium dilakukan dengan menggunakan jangka sorong berdasarkan metode Evans (1993). Hasil pengukuran ditampilkan dengan diagram batang dan dianalisis menggunakan Microsoft Excel 2010. Musang tidak memiliki processus paracondylaris, bentuk crista sagittalis externa dan crista nuchalis yang tidak menonjol. Struktur anatomi cranium musang mirip dengan anjing tipe mesaticephalic, yang membedakan adalah bentukan facial length yang lebih pendek. Analisis variabel pengukuran dan index menunjukkan adanya perbedaan signifikan antara cranium musang betina dan jantan.

The Common Palm Civets (Paradoxurus hermaphroditus) are carnivorous animals classified in the family of Viverridae. It is classified as Appendix-III in CITES (Convention on International Trade in Endangered Spesies). The population of these animals are found throughout Java, Sumatera, Kalimantan, Sabah, Serawak, Nusa Tenggara, Sulawesi, Asia Tenggara, Sri Lanka and India. The studies of cranial osteology of the Common Palm Civet are still uncommon. This research aims for gaining the knowledge of the macroscopic anatomy of the Common Palm Civet's cranium and which is including the study of the osteologic morphology and morphometry. This research used 5 craniums of Common Palm Civets with the average weight of less than a kilogram. The Common Palm Civets were gathered from the region of Muntilan and Yogyakarta. The study of morphology was done by analysing the morphology of the civet cranium and compare it to the cranium of dogs. The study of morphometry was conducted by measuring the length and the width, and by calculating the index of certain measuring points. The morphometric of the cranium was completed by using a vernier calliper based on Evans method (1993). The results were interpreted using Microsoft Excel 2010 and represented in a bar chart. Civet has no processus paracondylaris, less prominent of crista sagittalis externa and crista nuchalis. The anatomic structure of structure of civet is similar with mesaticephalic-type dogs. The difference among them is that civet has shorter facial length. The result of variable analysis and index shows significant differences between female and male cranium civet.
