| Abstract: |
<p>In the middle of March 2006, four isolated deciduous teeth were accidentally found by a local farmer nearby Glagah Ombo village of northern Sangiran. Geologically, the specimens were found on the calcareous sandy-clayey soil of the Grenzbank zone of Bapand (Kabuh) Formation. Later, these specimens were labeled as GLOM (acronym from Glagah Ombo) 2006.03
consist of GLOB 1 (right upper deciduous first incisor), GLOM 2 (left lower deciduous first molar), GLOM 3 (right upper diciduous second molar), and GLOM 4 (left upper deciduous second molar).</p> <p>In this study, we compared the GLOM 2, GLOM 3, and GLOM 4 with two of von Koenigswald's collections that are FS 67 and FS 7-13, which it is now housed at the Senckenberg Museum, Frankfurt (Germany). </p> <p>The crown shape index of GLOM 2 is similar to that of <i>H. habilis</i> and FS 67, but differs from the other specimens. However, in the context of size the GLOM 2 is similar to the sizes of FS 67 and <i>H. erecutus</i>'s specimens. The size of FS 7-12 is comparable to GLOM 4 rather than GLOM 3. But, based on the crown shape index FS 7-12 falls within the limit of GLOM 3 and LOM 4.</p> <p>Non-metrical comparison shows that GLOM 2 differs from FS 67 in the number of cusps, the configuration on trigonid versus talonid, the trigonid's shape, the arrangement of protoconid against the metaconid and in the aspect of turberculum molare. Meanwhile, GLOM 3 and GLOM 4 differ from FS 7-13 in the aspect of the biggest and smallest cusp
the position of the small cusp on the mesial cusp
configuration of distal marginal ridge and distal trigon crest.</p>
